Are you going to Windows 2008 R2 or Windows 2008? If you are going to
Windows 2008 R2 you need to upgrade to 6.5.5 (for compatibility
reasons).

My upgrade path would look something like:

1. Run consistency check per NBU 7.0 Upgrade instructions.
http://support.veritas.com/docs/340464
2. Create hot catalog backup of original master.
3. Install NetBackup 6.5.5 on new master (NetBackup 6.5.3 for non-R2).
4. Restore hot catalog backup to new master. (Might want to run another
consistency check here.)
5. Upgrade new master to 7.0

That could take a while depending on your catalog size, but if anything
goes wrong along the way you can always go back to your original master.

Subject: [Veritas-bu] Can NBU 6.5 database be imported into NBU 7 /
Upgrade with fresh O/S & NBU install steps

Hi Experts

We are looking at options to upgrade existing NBU 6.5.3 environment with

Win 2003 Master to NBU 7.
The easiest would obviously be  straight upgrade. But we'd also like to 
upgrade Win 2003 to 2008 (by doing fresh install) at the same time. NBU 
6.5 is currently installed onto a separate drive.

If we are to re-install everything from scratch ...
1. Is it possible to import 6.5.3 database straight into NBU 7?
2. Do we need to restore registry entries?
3. Will installing NBU 7 binaries on top of 6.5 do the trick (as the 
exisiting version is on a separate disk and will not be touched by Win 
2008 upgrade) ? I wonder if NBU install program will realise this is 
actually an upgrade (though registry entries are not present).

Regards

Glen
