Migrate Appliances (Within Maintenance Window)

You can run the e2e-migrate CLI within the maintenance window, which takes backup and migrates data from old appliances to new appliances.

Note:

By default, the migration tool does not delete any old backups attempted to preserve data. If backup exists, it is reused in retry attempts. You can provide -c option to cleanup up the existing backups before taking fresh backup.

Important:

Do not specify <-i option> here because the appliances are already deployed.
