 ### Added
 
 - Add `SnapAccountService` ([#8414](https://github.com/MetaMask/core/pull/8414))
-- Add `SnapPlatformWatcher` and `SnapAccountService.ensureReady` ([#8715](https://github.com/MetaMask/core/pull/8715)), ([#8725](https://github.com/MetaMask/core/pull/8725))
+- Add `SnapPlatformWatcher` and `SnapAccountService.ensureReady` ([#8715](https://github.com/MetaMask/core/pull/8715)), ([#8725](https://github.com/MetaMask/core/pull/8725)), ([#8732](https://github.com/MetaMask/core/pull/8732))
   - Waits for the Snap platform to be ready and for a Snap keyring to appear in `KeyringController` state before allowing Snap account operations.
   - Callers must ensure `init()` has run and the Snap is currently installed, enabled, non-blocked, and declares `endowment:keyring`.
   - `SnapAccountService.ensureReady` now awaits the watcher, so it only resolves once both conditions hold (or rejects if the Snap keyring does not appear within the configured timeout).
   - `SnapAccountService.ensureReady` now throws `Unknown snap: "<id>"` when called with a Snap ID that isn't tracked as an account-management Snap.
+  - `SnapAccountService.ensureReady` now automatically creates the Snap keyring (v2) for a given Snap ID if it was not available.
 - Add `config` option to `SnapAccountService` constructor with a `snapPlatformWatcher` field exposing `ensureOnboardingComplete` and `snapKeyringWaitTimeoutMs` ([#8715](https://github.com/MetaMask/core/pull/8715))
   - Export `SnapAccountServiceConfig` and `SnapPlatformWatcherConfig` types.
 - Add `@metamask/keyring-controller` dependency ([#8715](https://github.com/MetaMask/core/pull/8715))

   - This logic used to live on the clients.
   - The service messenger now requires the `KeyringController:unlock`, `AccountTreeController:selectedAccountGroupChange`, `AccountTreeController:accountGroup{Created,Updated,Removed}` events.
   - The service messenger now requires the `AccountTreeController:getSelectedAccountGroup` and `AccountTreeController:getAccountGroupObject` actions.
+- Add `migrate` ([#8732](https://github.com/MetaMask/core/pull/8732))
+  - The migration is guaranteed to be run when using `ensureReady`.
+  - It is conccurent-free and can safely be called by multiple execution flows.
+  - Once the migration has ran, the legacy Snap keyring will be emptied, thus, consumers are expected to use the new per-Snap keyring (v2) instances instead.
