NBU 7.5 - Replace Legacy NBU environment with 5220 Appliances
I have an existing site which has a Virtual Master Server and three Media Servers - all at 7503 - and using locally attached disk storage units accross SAN. I am replacing the environment with 2 x 5220 appliances - using AIR for replication.
My question is around migration of images between the old and the new environment. I am not concerned about the daily/weekly backup images as they will expire over the short term, and in the interim the old environment will be available for restore if required. I am looking as to the best way to migrate the monthly/yearly images from the existing system to the new appliances.
I have considered the two following options for implementation:
1. Add the local appliance as a new NBU domain, as a Master/Media, and manually add the policies to this new environment thereby migrating the clients on a phased basis.
2. Add the appliance to the existing NBU domain as a media server, and simply change the policy destination (as I will be introducing SLP's anyhow as part of this)
If I take option 2 then as far as I believe I won't be able to 'duplicate' backup images from the existing storage units to the appliance as the storage units do not belong to the same media server - correct ?
Any advices ?
