remove old target data and update script

[johndcollett]

Background

(Provide a link to any relevant issues AND provide a TLDR of the issue in this pull request)

we no longer generate the targets in versioned folders and because of the old data when transferring files over the newwer data was being overwritten by the stale data

Solution

delete the old data
update the script to move things over to not look for versioned folders

🚨🚨🚨 Docs migration in progress 🚨🚨🚨

We are actively migrating UI extension reference docs to MDX in the areas/platforms/shopify-dev zone of the monorepo. This impacts docs for the following surfaces:

• Admin UI extensions
• App Home
• Checkout UI extensions
• Customer account UI extensions
• POS UI extensions

During this migration, please be aware of the following:

.doc.ts files are being deprecated. Changes to .doc.ts files in this repo will not be reflected in the new MDX-based docs. If you need to update docs for a reference that has already been migrated, make your changes directly in the areas/platforms/shopify-dev zone of the monorepo instead.

Doc comments in .ts source files (the comment blocks above types and functions) are also affected. Generating docs from these comments currently requires a newer version of the @shopify/generate-docs library that isn't yet available. Updates to doc comments may not produce the expected output until the migration is complete.

Examples that previously lived in this repo are being moved to the areas/platforms/shopify-dev zone of the monorepo and should be authored there going forward.

What should I do?

• If your PR includes changes to .doc.ts files, doc comments, or examples, please reach out to us in #devtools-proj-templated-refs so we can help ensure your updates are captured correctly.
• If your PR is limited to source code changes (non-docs), you can ignore this notice.

Thanks for your patience while we complete the migration! 🙏

This PR targets a stable release branch (2026-04). Once merged, the change typically also needs to be forward-ported to 2026-07-rc so it ships in the next release.

When you open the forward-port PR, include a line like this in its body so the needs-rc-port label gets removed automatically when that PR merges:

Forward-port of #4443

Accepted formats (comma-separated for multiple):

• #4443
• GH-4443
• 4443
• https://github.com/Shopify/ui-extensions/pull/4443

If a forward-port isn't needed (e.g., the change is stable-only), you can remove the needs-rc-port label manually.
