-3. **09:55**: Take another snapshot of the old cluster and restore it to the new cluster. Repeat this process until the snapshot and restore operations take only a few seconds or minutes. Remember that, when restoring indices that _already_ exist in the new cluster (e.g. to pull in recently copied data), they need to be [closed](/deploy-manage/tools/snapshot-and-restore/restore-snapshot#considerations). Also remember that the restore operation automatically opens indices, so you will likely need to close the actively written ones after restoring them.
