I have not run NOM server myself

But I think higher version of NOM server will work fine with lower version of NBU master servers.

If I were you, I'd upgrade the NOM server first.

I hope it will work but the link I posted above states that it is not supported.

I don't quite understand the dilemma.
NOM supports multiple versions of NetBackup masters.

Yes, you are right - the documentation you quoted does say this...

= = =
NOM 6.5 release updates also have backward compatibility with NetBackup 6.0 MP5 and above. See the table below.
= = =

I'm not sure how critical your NOM operation is to your organization, but if you can't afford NOM downtime at all, then yes it will be a good idea to do the "skinny upgrade" of the master to MP5, then upgrade NOM to 6.5 and upgrade master again.

Well, all backup admins (you and me, all of us) are encouraged to apply latest MP anyway.

:-)

Thinking about this logically

NOM has to sit on a netbackup client (can be on a media server but not recommended due to performance issues)

A netbackup client should never be a higher version than its master

Therefore you should upgrade the master first and then the client on the NOM server and then NOM 

All other clients can then be upgraded when convenient

The key part to my dilema is that backward compatibility starts from 6.0 MP5 onwards.
My whole environment is 6.0 MP4.

100% uptime is not critical as such but I have worked hard to get NOM useful, with a dozen or so daily reports going out to various managers and remote site support staff.

If the upgrades to 6.5.4 take a few weeks, having NOM fail for this duration reflects badly on my team.

I have virtualised NOM. I am testing the upgrade. Using VM snapshots, I can roll back in time in an instant. This way I can determine if the backward compatibility issues are minor or major & then make a risk management decision from this.

thx

Its only the masters that need to be at mp5 or above as you are extracting info from the masters databases

if you only have one master then that needs to be at 6.5.4 if thats the version the NOM server will be at

yes i know this

I have 1x AIX master & 9x Win32 masters in remote locations

thats too much effort to go 6.5.4 in a big bang

a skinny MP is much less effort

Yep that sounds like the best option for you Richard.

All of your 10 masters are managed by the same one NOM server right.

Then the first line and the third line in the DAY 2 will need to be merged in to one line.

Abe

Thx guys.

Yes 1 NOM for all masters.
Agreed. MP7 it is.
We have a plan!
