Re: [Veritas-bu] Netbackup 7.1 Migration

What we did was to simply build a new master with new name/IP and continue to
run the old master along side it allowing natural aging of policies/recalls
from offsite storage for vaulting for 3-4 months then we shutdown the old
server. This means for any older backups we'd want to restore we'd have to
import the tape into the new master. We chose to do it this way because old
master was controlling a library with LTO1 drives whereas new environment was
mostly LTO5 which won't read LTO1s anyway so we also have a couple of LTO3s in
case we need to import one of the LTO1s.
The research I did at the time indicated there really is NO good way to use new
name/IP with old Catalog without paying ransom to Symantec. I saw comments
from some then that they had tried to do it anyway and although it initially
appeared to work months later they began having issues related to the attempt.
You'll find folks that say they've done it but if you look carefully at those
old posts you'll see it was mostly for NBU versions 3.x and nothing newer.

I also followed this path - same name/same IP.
The old server was left on the network while the hot catalog ran. When that
finished, I removed the old master from the network, plugged in the new master,
restored the catalog and away we went.
In reality, it was fairly painless.
I heard a lot of bad things about changing the name/IP so I didn't want to go
there.

The plan I went with was to build the new hardware 1st and give it the same
name and IP address as the original master server. Install the same NetBackup
version as the old server. Complete a hot catalog backup on the old server,
then take it offline. Bring the new master server online and restore the
catalog backup. Then upgrade the NetBackup version. This path is approved by
Symantec and does not involve Symantec personnel in any fashion.
The media servers will recognize the new master immediately because it has the
same DNS name and IP address, and there will be very minimal downtime.

Subject: [Veritas-bu] Netbackup 7.1 Migration
Hello Everybody.
We have implemented Netbackup 7.1 for backups. We have 1 master
server(standard) on Solaris-10 and 12 clients(standard). We are going to
upgrade the master server to Enterprise and one of the clients to Enterprise.
Once this is completed, we have to migrate the master server to another
physical server. The physical server has all the hardware same as the existing
hardware.
The hostname and IP address will change.
I read through the below TNs:
http://www.symantec.com/docs/TECH31385
http://www.symantec.com/docs/TECH77448
It says, "Moving a Master Server to a new machine involving a host name change"
Netbackup master hostname is deeply embedded in each part of Netbackup config
and EMM database.
Only a trained Consulting Partner can change this hostname.
Can anyone please help me perform this migration without involving Symantec
consultants.
It would be very helpful if anyone could provide the steps needed to perform
the migration or if any document is available.These kind of migrations must be
done frequently around Netbackup customers so I am hoping there are some
Netbackup gurus who has performed the migrations and could provide some good
advice.
Thanks in advance
Regards
Sri
