We used a variation on this here. We stood up a new master, then waited
1 year for 99% of our images to expire. Then we imported the old media
(SLT) on the new master and duplicated them to new media (LTO). Just
keep in mind that when you do this, you need to make sure the retentions
match on the old and new masters. If retention 10 on your old master is
infinity and retention 10 on the new master is 1 year, the images will
only be kept for 1 year on import.

Good luck!

I would think that keeping the current server would be an option for
you.
I would have done the same if we didn't have a multitude of images saved
to infinity...
Our old master would have been around forever, so I just did the
migration...
Good Luck!

Thank You all for your replies. I have to change the hostname and IP
address, there is no other option. We currently have installed the
master server on a production server. Its not a dedicated backup server.
The new server we are planning is a dedicated NBU master server. So the
hostname will change from the current server :-(

I think i would go with Jeff' idea of building new server from scratch
and importing media from old server to new server in case of restore
requests. 

Can we use the option of keeping current server and as well as new
server till the data on the current tapes expire?
Remove all the tapes from current server and keep it write protected.
Stop the NBU services on current server. Whenever a restore request
comes, stop the services on new server and restore data from old server.


Thanks
Sri
