Today I want to show you Enterprise Live Migration—we call it ELM. +> +> ELM moves Azure DevOps repositories to GitHub Proxima with zero downtime. Here's what makes it different: the migration is *live*. +> +> What does that mean? Your source repository stays active. Your teams keep working while we continuously sync changes to GitHub in real-time. Then at a time you choose, we execute cutover—the source becomes read-only, GitHub becomes the source of truth. +> +> We migrate everything with full fidelity: all git history, branches, tags, pull requests, comments, reviews. No data loss whatsoever. +> +> Let me show you the happy path in about three minutes. We'll validate, promote, schedule, and execute. Let's go to the terminal. + +--- + +## Live Demo (0:30–2:50) + +### Step 1: Create & Validate Migration (0:30–1:15) + +**What to say BEFORE running the command:** + +> So let's start. First step is validation. I'm going to create a migration, but in validate-only mode. This means we run all pre-flight checks without actually moving data yet. We check things like: does the target repository already exist? Is the agent pool configured? Are there too many active pull requests? It's a safety net. +> +> Here's the command: + +**Run this command:** +```bash +az devops migrations create \ + --org https://dev.azure.com/mseng \ + --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ + --target-repository https://msft.ghe.com/1ES/ELMProximaValidation \ + --validate-only +``` + +**What to say WHILE waiting for output:** + +> This creates the migration request. Notice three things: we pass the organization, the source repository ID, the target GitHub URL, and the `--validate-only` flag. That flag is important—it tells ELM "don't move data yet, just check if this repository is safe to migrate." + +**After the command completes, immediately run the status check:** +```bash +az devops migrations status \ + --org https://dev.azure.com/mseng \ + --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 +``` + +**What to say AFTER seeing the status output:** + +> Perfect! Look at the output. The stage is now `Synchronization` and status is `Succeeded`. That means: +> - All pre-flight checks passed ✓ +> - Code has already synced to the target ✓ +> - Pull requests are synced ✓ +> +> Now we know this repository is safe to migrate. The validation phase is complete. Ready to move to the next step? + +--- + +### Step 2: Promote & Schedule Cutover (1:15–2:00) + +**What to say BEFORE running these commands:** + +> Great! Validation passed. Now step two: I'm going to do two things at once. +> +> First, I promote this from validate-only mode to a *real* migration. That means we start continuous synchronization—any new commits, PRs, or changes in the source will continuously sync to GitHub until we tell it to stop. +> +> Second, I schedule the cutover time. This is when the switch happens—source becomes read-only, GitHub becomes the active repository. + +**Run the promote command:** +```bash +az devops migrations resume \ + --org https://dev.azure.com/mseng \ + --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ + --migration +``` + +**What to say WHILE the first command runs:** + +> This command promotes the migration from validate-only to full. Notice the `--migration` flag—that tells ELM "take this validated setup and start the real migration." + +**Now run the cutover schedule command:** +```bash +az devops migrations cutover set \ + --org https://dev.azure.com/mseng \ + --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ + --date 2026-05-06T21:05:00Z +``` + +**What to say AFTER both commands complete:** + +> Excellent. What just happened: +> - The migration is now LIVE—we're syncing everything continuously +> - Cutover is scheduled for 21:05:00 UTC +> - At that time, the cutover will execute automatically +> +> The system is now doing continuous sync in the background. All new code, PRs, everything flows to GitHub in real-time. Teams can still work in Azure DevOps—they won't be interrupted until cutover actually executes. + +--- + +### Step 3: Complete & Verify (2:00–2:50) + +**What to say BEFORE this final check:** + +> Now we wait for cutover to complete. In a real migration, you might wait hours or days. But in this demo, we scheduled it for just a few moments from now. Let me check the current status to see if we've reached the finish line. + +**Run the final status check:** +```bash +az devops migrations status \ + --org https://dev.azure.com/mseng \ + --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ + --query "{Stage:stage, Status:status, CodeSync:codeSyncDate, LastUpdate:changedDate}" +``` + +**What to say AFTER seeing the output:** + +> There it is. Stage is `Migrated`. Status is `Succeeded`. Here's what this means: +> +> ✅ All code migrated successfully +> ✅ All pull requests migrated successfully +> ✅ All git history preserved +> ✅ Source repository is now read-only +> ✅ GitHub is now the authoritative repository +> +> The cutover is done. The repository has moved from Azure DevOps to GitHub Proxima. Teams will now switch to working in GitHub. No data loss, no downtime. +> +> That's the happy path—validate, promote, schedule, execute, done. Questions? + + + +--- + +## Closing (2:50–3:00) + +**What to say to wrap up:** + +> So that's Enterprise Live Migration in action. Four commands, about three minutes, and the repository is safely moved from Azure DevOps to GitHub. +> +> The key points: +> - **Validation first** catches problems before you migrate data +> - **Live sync** means your teams aren't blocked +> - **You control the timing** of cutover +> - **Full data fidelity**—nothing is lost +> +> If you need to migrate repositories, ELM handles it safely and efficiently. Thanks for watching! + +--- + +## Key Talking Points (Reference) + +Use these if questions come up: + +**Q: What if validation fails?** +> You fix the blocker and try again. It's just validation—no data moved, no harm done. + +**Q: Can teams still work during the sync phase?** +> Yes. That's the whole point of "live migration." The source stays active. Teams work normally until cutover. + +**Q: What happens at cutover?** +> The source becomes read-only, GitHub becomes writable, and sync stops. Usually takes a few seconds to a few minutes. + +**Q: Is there data loss?** +> No. We migrate everything with full fidelity: full git history, all PRs with comments, reviews, everything. + +**Q: How long does validation take?** +> Typically 30 seconds to a few minutes depending on repo size and complexity. + +**Q: Can I cancel a migration?** +> Yes, use `az devops migrations abandon`. The source stays active. + +--- + +## Quick Reference + +**All commands in one block:** +```bash +ORG="https://dev.azure.com/mseng" +REPO="1c01b5a0-9479-4d6a-8317-1307181cf524" +TARGET="https://msft.ghe.com/1ES/ELMProximaValidation" + +# 1.

Migration Workflow Matrix

Complete mental model for operators and repo owners — stages, outcomes, and decision gates

+
+ +
+ + + +
+ + +
+ +
+

🧠 Mental Model: How Migrations Work

+
    +
  • Your job (Operator): Run the repo through 4 stages: validate → copy code → review issues → execute cutover
    • +
  • Repo Owner's job: Review the code on GitHub (visible during sync) and approve or reject it
    • +
  • The simple flow: Does it look safe to migrate? → Copy to GitHub (owner can see) → Check what broke → Does owner approve? → Make GitHub the authoritative source
    • +
  • GitHub goes LIVE: Only during cutover execution. Before that, Azure DevOps is still the source teams must work in.
    • +

📋 Key Behaviors to Know

+
+
+ Validate without committing Operator +

You can run a full pre-flight check before starting any real sync. If it fails, nothing has been started and there's nothing to clean up. If it passes, you decide whether to proceed. Good practice before committing to a migration.

+
+
+ Pausing a migration Operator +

Freezes the sync at its current point. Azure DevOps stays fully writable — teams keep working normally. GitHub code is frozen at the last sync point. No data is lost. You can pause at any active stage (sync or cutover prep).

+
+
+ Resuming after a pause Operator +

Picks up exactly from where it left off. Any new commits or PRs made in ADO while paused will be picked up automatically and synced to GitHub.

+
+
+ Abandoning a migration Operator +

Permanently deletes the migration. Azure DevOps goes back to read-write. GitHub keeps whatever code was copied but it's not live or authoritative. You can start a completely new migration for the same repo afterward.

+
+
+ Cancelling a scheduled cutover Operator +

Removes the scheduled date but the migration stays in "approved" state (ReadyForCutover). You don't need to re-approve — just pick a new date and reschedule.

+
+
+ Skipping a validation failure Operator + Repo Owner +

Some validation failures can be skipped (e.g., too many open PRs, target repo already exists). The repo owner must accept the risk and authorize the skip. Operator then retries with the skip flag set.

+
+
+ 48-hour notice before cutover Repo Owner +

Teams are notified at least 48 hours before GitHub goes live. Owners should use this window to close open work, merge critical PRs, and make sure their team is ready to switch to GitHub.

+
+
+ ADO is read-only during cutover execution Repo Owner +

The 5-10 minute cutover window is a hard downtime. No one can push code to Azure DevOps during this time. Plan for it — alert your team in advance to avoid lost work during the switch.

📋 Key Behaviors to Know

-
-
- Validate without committing Operator -

You can run a full pre-flight check before starting any real sync. If it fails, nothing has been started and there's nothing to clean up. If it passes, you decide whether to proceed. Good practice before committing to a migration.

-
-
- Pausing a migration Operator -

Freezes the sync at its current point. Azure DevOps stays fully writable — teams keep working normally. GitHub code is frozen at the last sync point. No data is lost. You can pause at any active stage (sync or cutover prep).

-
-
- Resuming after a pause Operator -

Picks up exactly from where it left off. Any new commits or PRs made in ADO while paused will be picked up automatically and synced to GitHub.

-
-
- Abandoning a migration Operator -

Permanently deletes the migration. Azure DevOps goes back to read-write. GitHub keeps whatever code was copied but it's not live or authoritative. You can start a completely new migration for the same repo afterward.

-
-
- Cancelling a scheduled cutover Operator -

Removes the scheduled date but the migration stays in "approved" state (ReadyForCutover). You don't need to re-approve — just pick a new date and reschedule.

-
-
- Skipping a validation failure Operator + Repo Owner -

Some validation failures can be skipped (e.g., too many open PRs, target repo already exists). The repo owner must accept the risk and authorize the skip. Operator then retries with the skip flag set.

-
-
- 48-hour notice before cutover Repo Owner -

Teams are notified at least 48 hours before GitHub goes live. Owners should use this window to close open work, merge critical PRs, and make sure their team is ready to switch to GitHub.

-
-
- ADO is read-only during cutover execution Repo Owner -

The 5-10 minute cutover window is a hard downtime. No one can push code to Azure DevOps during this time. Plan for it — alert your team in advance to avoid lost work during the switch.

Today I want to show you Enterprise Live Migration—we call it ELM. -> -> ELM moves Azure DevOps repositories to GitHub Proxima with zero downtime. Here's what makes it different: the migration is *live*. -> -> What does that mean? Your source repository stays active. Your teams keep working while we continuously sync changes to GitHub in real-time. Then at a time you choose, we execute cutover—the source becomes read-only, GitHub becomes the source of truth. -> -> We migrate everything with full fidelity: all git history, branches, tags, pull requests, comments, reviews. No data loss whatsoever. -> -> Let me show you the happy path in about three minutes. We'll validate, promote, schedule, and execute. Let's go to the terminal. - ---- - -## Live Demo (0:30–2:50) - -### Step 1: Create & Validate Migration (0:30–1:15) - -**What to say BEFORE running the command:** - -> So let's start. First step is validation. I'm going to create a migration, but in validate-only mode. This means we run all pre-flight checks without actually moving data yet. We check things like: does the target repository already exist? Is the agent pool configured? Are there too many active pull requests? It's a safety net. -> -> Here's the command: - -**Run this command:** -```bash -az devops migrations create \ - --org https://dev.azure.com/mseng \ - --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ - --target-repository https://msft.ghe.com/1ES/ELMProximaValidation \ - --validate-only -``` - -**What to say WHILE waiting for output:** - -> This creates the migration request. Notice three things: we pass the organization, the source repository ID, the target GitHub URL, and the `--validate-only` flag. That flag is important—it tells ELM "don't move data yet, just check if this repository is safe to migrate." - -**After the command completes, immediately run the status check:** -```bash -az devops migrations status \ - --org https://dev.azure.com/mseng \ - --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 -``` - -**What to say AFTER seeing the status output:** - -> Perfect! Look at the output. The stage is now `Synchronization` and status is `Succeeded`. That means: -> - All pre-flight checks passed ✓ -> - Code has already synced to the target ✓ -> - Pull requests are synced ✓ -> -> Now we know this repository is safe to migrate. The validation phase is complete. Ready to move to the next step? - ---- - -### Step 2: Promote & Schedule Cutover (1:15–2:00) - -**What to say BEFORE running these commands:** - -> Great! Validation passed. Now step two: I'm going to do two things at once. -> -> First, I promote this from validate-only mode to a *real* migration. That means we start continuous synchronization—any new commits, PRs, or changes in the source will continuously sync to GitHub until we tell it to stop. -> -> Second, I schedule the cutover time. This is when the switch happens—source becomes read-only, GitHub becomes the active repository. - -**Run the promote command:** -```bash -az devops migrations resume \ - --org https://dev.azure.com/mseng \ - --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ - --migration -``` - -**What to say WHILE the first command runs:** - -> This command promotes the migration from validate-only to full. Notice the `--migration` flag—that tells ELM "take this validated setup and start the real migration." - -**Now run the cutover schedule command:** -```bash -az devops migrations cutover set \ - --org https://dev.azure.com/mseng \ - --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ - --date 2026-05-06T21:05:00Z -``` - -**What to say AFTER both commands complete:** - -> Excellent. What just happened: -> - The migration is now LIVE—we're syncing everything continuously -> - Cutover is scheduled for 21:05:00 UTC -> - At that time, the cutover will execute automatically -> -> The system is now doing continuous sync in the background. All new code, PRs, everything flows to GitHub in real-time. Teams can still work in Azure DevOps—they won't be interrupted until cutover actually executes. - ---- - -### Step 3: Complete & Verify (2:00–2:50) - -**What to say BEFORE this final check:** - -> Now we wait for cutover to complete. In a real migration, you might wait hours or days. But in this demo, we scheduled it for just a few moments from now. Let me check the current status to see if we've reached the finish line. - -**Run the final status check:** -```bash -az devops migrations status \ - --org https://dev.azure.com/mseng \ - --repository-id 1c01b5a0-9479-4d6a-8317-1307181cf524 \ - --query "{Stage:stage, Status:status, CodeSync:codeSyncDate, LastUpdate:changedDate}" -``` - -**What to say AFTER seeing the output:** - -> There it is. Stage is `Migrated`. Status is `Succeeded`. Here's what this means: -> -> ✅ All code migrated successfully -> ✅ All pull requests migrated successfully -> ✅ All git history preserved -> ✅ Source repository is now read-only -> ✅ GitHub is now the authoritative repository -> -> The cutover is done. The repository has moved from Azure DevOps to GitHub Proxima. Teams will now switch to working in GitHub. No data loss, no downtime. -> -> That's the happy path—validate, promote, schedule, execute, done. Questions? - - - ---- - -## Closing (2:50–3:00) - -**What to say to wrap up:** - -> So that's Enterprise Live Migration in action. Four commands, about three minutes, and the repository is safely moved from Azure DevOps to GitHub. -> -> The key points: -> - **Validation first** catches problems before you migrate data -> - **Live sync** means your teams aren't blocked -> - **You control the timing** of cutover -> - **Full data fidelity**—nothing is lost -> -> If you need to migrate repositories, ELM handles it safely and efficiently. Thanks for watching! - ---- - -## Key Talking Points (Reference) - -Use these if questions come up: - -**Q: What if validation fails?** -> You fix the blocker and try again. It's just validation—no data moved, no harm done. - -**Q: Can teams still work during the sync phase?** -> Yes. That's the whole point of "live migration." The source stays active. Teams work normally until cutover. - -**Q: What happens at cutover?** -> The source becomes read-only, GitHub becomes writable, and sync stops. Usually takes a few seconds to a few minutes. - -**Q: Is there data loss?** -> No. We migrate everything with full fidelity: full git history, all PRs with comments, reviews, everything. - -**Q: How long does validation take?** -> Typically 30 seconds to a few minutes depending on repo size and complexity. - -**Q: Can I cancel a migration?** -> Yes, use `az devops migrations abandon`. The source stays active. - ---- - -## Quick Reference - -**All commands in one block:** -```bash -ORG="https://dev.azure.com/mseng" -REPO="1c01b5a0-9479-4d6a-8317-1307181cf524" -TARGET="https://msft.ghe.com/1ES/ELMProximaValidation" - -# 1.

In real scenarios, it depends on repo size and complexity. (Pause a moment.) Let me check the detailed error output. - -**What to run:** -```powershell -az devops migrations status --org https://dev.azure.com/ORG --repository-id SOURCE_REPO_GUID -o json -``` - -**Look for:** `statusDetails` or `failureReason` fields. - ---- - -### Scenario: Create fails with "repo not found" -**What to say:** -> If the source repo is not found, it could be disabled or you may lack permissions. Let me quickly verify repo access. - -**What to run:** -```powershell -az repos show --org https://dev.azure.com/ORG --project PROJECT_NAME --repository SOURCE_REPO_GUID -``` - -**Expected:** Repo metadata with `isDisabled: false`. -**If failed:** Check repo is enabled and accessible in ADO UI. - ---- - -### Scenario: Create fails with "403 / Manage enterprise live migrations permission" -**What to say:** -> This is a permissions issue. The caller needs the "Manage enterprise live migrations" permission on that repository. That's a granular permission we grant at the repo level for safety. - -**Resolution:** Grant permission in ADO > Project Settings > Repositories > [Repo] > Security. - ---- - -### Scenario: Cutover set fails with "Invalid date format" -**What to say:** -> Cutover date must be ISO 8601 format. - -**Example valid dates:** -- `2026-05-04T20:00:00Z` (UTC) -- `2026-05-04T20:00:00-07:00` (with timezone offset) - ---- - -## Demo Success Criteria - -- [ ] Validation completes successfully -- [ ] Promotion to full migration succeeds (validateOnly → false) -- [ ] Cutover date is set -- [ ] Final status shows Migrated stage (or will after real cutover) -- [ ] ADO repo read-only banner is visible -- [ ] Proxima repo shows all branches/PRs/history - ---- - -## References - -- **Full TSG:** `doc/elm_migrations_tsg.md` -- **CLI Help:** `az devops migrations --help` -- **API Version:** 7.2-preview (`/_apis/elm/migrations`) - ---- - -## Notes for Presenter - -- **If validation is slow:** Say: "In production this typically runs in seconds to minutes.
