Chapter 8. Storage migration using the Kube Storage Version Migrator
Storage version migration is used to update existing objects in the MicroShift node from their current version to the latest version. The Kube Storage Version Migrator embedded controller is used in MicroShift to migrate resources without having to re-create those resources. Either you or a controller can create a StorageVersionMigration
custom resource (CR) that requests a migration through the Migrator Controller.
