MTree replication for Netbackup Disk pool (OST)

We are performing a MTree replication for DDBoost over FC integrated with Netbackup.

Regarding the redirection from Netbackup side. the below points will be followed to perform this task. please confirm that this is correct or needs some modification.

1. Perform MTree replication from DD1 to DD2.
2. Once completed , stop all the backups job from Netbackup side and break off the replication context.
3. Convert the MTree back to DD Boost storage units on the new DD by following the below commands.

# ddboost user assign

# ddboost storage-unit modify user

1. Disable DDBoost on the source DD and make sure that NetBackup is unable to communicate with DDBoost storage unit over IP Address / DFC-server-name. (disable the ethernet ports related to this configuration)
2. Configure the same DDBoost username / password on the new DD, and the same DDBoost DFC-server-name / IP address.
3. Reauthenticate the connection from NetBackup side and make sure that that volumes are accessible from the new DD. Perform a test backup/restore to make sure that everything is fine.
