Migrating Images between Netbackup Domains
I have a requirement whereby we are replacing 4 x 50x0 Puredisk Appliances with 4 x 5220 Appliances. The current config has all devices in the same Netbackup domain, even though 2 of the 50x0 appliances are in a remote location. Each pair of 50x0 appliances is presented as a single pool within Netbackup.
We are implementing the new 5220 appliances in an AIR configuration - therefore there will be two distinct NBU domains (one production and one DR). The current master server will remain in the production site, with one of the 5220 appliances in DR acting as the Master server in the other NBU domain.
My issue is in migrating the data from the current 50x0 appliances to the new 5220 appliances. In the production site the images can simply be duplicated from the 50x0's to the 5220's, as they are all in the same NBU domain. But when considering migrating the images from the remote 50x0's (which are part of the original production NBU domain) to the new 5220's in the new NBU domain - what are the best options here ? The environment does not include any tape devices.
