Migrating Master Server to new hardware

I need to migrate my Master server from Windows server 2003 x86, running Netbackup 7.5 to Windows Server 2008 R2 running Netbackup 7.6

I have found the following documents:

I would say that I am fairly happy with migrating our 2003 x86 master server (EMM) to a 2008 R2 x64 O/S, however the thing that’s concerning me is that my image DB is on a different drive partition to the NB installation drive, which was completed by using the ALTPATH method listed In the link above.

I believe that I need my Image DB to be on the same drive as the NB installation prior to backing up my catalog in readiness for the move, so I have an idea on how to get around this which is a bit of a bodge. Would anyone have best practise suggestions on how to accomplish this?

Any help with documents for this migration would be appreciated.
