Just to be clear - we kept the old master running so it could continue to do 
vaulting reports to recall media from offsite as they expired.   If you're not 
doing vaulting this may not be a consideration for you.

We didn't do the 1 year Jonathan suggests - our intent was to do 3 months since 
most of our monthlies expire in that time frame.  In actuality it ended up 
being more than 6 months but that was just because we were slammed.   In our 
case we wanted to make the old master a media server for the new environment 
due to disk replications/backups we did there.  (It was HP-UX and we couldn't 
do the replications to Linux owing to filesystem/volume manager used on HP-UX 
and not on Linux.)

My question would be if the existing server is a "Production" server how are 
you backing up that "Production" stuff after you switch to the new master?   
That is to say, in our case we didn't have to keep any other app running on the 
old master and were able temporarily to move the disk replication to another 
HP-UX server.  In your case however you need to be concerned with this other 
"Production" stuff.   You can't run the old master as a master for the old 
environment AND as a  client/media server for the new environment as well.

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
