@jhadvig Just to confirm:

• You have something creating StorageVersionMigration in clusters, and that's been there for a few releases?
• You have something in cluster that is removing the v1alpha1 from .status.storedVersions once the migration is complete?

[jhadvig]

@JoelSpeed

1. yes - CONSOLE-3652: Create StorageVersionMigration for ConsolePlugin CRD v1 migration console-operator#816
2. yes - OCPBUGS-44362: Remove the v1alpha1 schema for ConsolePlugin CRD #2095 but you probably mean CONSOLE-4665: Disable serving of old v1alpha1 CRD version #2411 the issue was in fact that we needed to flip the switch on the served field .

The SVM i still there and once we vendor the removal of the old API by bumping the version in the console-operator repo will remove it.
