Just to add to my comments, if you are performing a "rolling" upgrade from
Win2k to Win2k3, the cluster should also get updated at the same time.
There is a process to follow in order to upgrade the last node of your
cluster, but I would have thought your Admins would have prepared for this
(ie: check list, documentation, research, ect).
 
How Exchange will behave, remains to be seen (hence why I stressed you cover
yourself!)
 
HTH

I forgot to mention that our Netbackup Master is at 5.1 MP5

 

Question 1

Is it possible to have different version of Windows OS and still perform
Backups and Restores, while failing over the package between the Exchange
nodes?

 

Is this supported by Veritas.

 

Kind Regards

The key thing here, is that if you have a latest MP on your client, then
your Master needs the same - as the latest MP will contain updates that your
earlier MP will possibly not know about!

 

What you should be doing is ensuring you are in a prime position to recover
BOTH nodes at its current setup, BEFORE any upgrade takes place (either from
a backup, flash image, drive image, ect) so you can rollback.

 

This way, your protecting yourself, as well as NetBackup, should the upgrade
go wrong.

 

But as a rule..... updates should be...

 

MP on Master

MP on Media Servers

MP on Clients

 

If you keep the same NBU Client on both nodes, it should work, and when both
are completed, you can then upgrade your environment to MP5 or later (think
6 is out now!).

 

HTH a bit !

The exchange team are upgrading there servers from Windows 2000 to Windows
2003.

 

During the upgrade process they are planning to have one node 1 at Windows
2000 and the other node at Windows 2003.

 

Netbackup is installed on the X:\ drive which is shared between the
clusters.

 

The version of Netbackup on each node is currently - 5.1 MP3

 

I have two questions from the Netbackup point of view:

 

Question 1

Is it possible to have different version of Windows OS and still perform
Backups and restores, while failing over the package between the nodes?

Question 2

Is it possible to have different versions of NB software on both nodes e.g?

            Windows 2000 5.1 MP3               Windows 2003   5.1 MP5
