Backup images migration between domains

I am currently working on a project including two distinct domains, each with its own Netbackup applianc eserving as a media server. Here is a brief overview:

Domain 1:

Master server :BYO, OS version  RHEL 8.10

NBU version : 10.3.0.1

Media server: Netbackup appliance, mode 5340. Version 10.3.0.1

Domain 2: 

Master server : BYO, OS version RHEL 7.9

NBU version : 8.2

Media server: NBU appliance, NBU version 8.2

we are planning to decommission domain 2 . However, the domain 2 appliance holds LTR images( 10 years) that we need to migrate before proceeding with the decommission.

i would like to explore potential image migration options and need your guidance

  1. Direct appliance to appliance migration across domains: Is it feasible to directly migrate images from appliance in domain 2 the appliance in domain 1, given that they are in different domain and running different Netbackup version and are different appliance model?
  2. Replication option across domains for existing backup images: Is it possible to replicate the existing images from domain 2 to domain 1? if Replication is a viable approach, could you please share the steps or process required to setup and execute this replication. Considering Difference in Netbackup version and appliance models.

    Hi,

    You'll have to use "nbreplicate" command to migrate LTR images from old domain to the new one. The first phase is to build a trust between master servers and then have old NBU appliance fetched CA/certificate from target master.

    You can pass the list of images as the parameter (Bidfile) on nbreplicate command to automate the process. You can use the following command to generate the list based on retention levels set on images.

    Change "-rl x" accordingly to search for images with 10 years of retention.

    bpimmedia -legacy -dp dp_med -stype PureDisk -rl 8 | grep ^IMAGE | awk '{print $4}'
