Your HPSUSAN will not change if it is a swap of cards within the same
chassis.  If you are talking about bringing in another machine and putting
it next to your old machine, then yes, the HPSUSAN number will change.  You
can think of it sort of like the VIN number on your car, you might get a new
engine but it is the same car.

What will change regardless of whether you are talking about a board swap in
the same chassis or a new chassis altogether is HPCPUNAME which will provide
the value of "SERIES 957XS" or "SERIES 987XS".

The key thing is to know what method of upgrade you are doing (card swap or
box swap) so that you know whether or not the HPSUSAN number is going to
change, and then contact the vendors for the software you have on your
system and get new validation codes to fit your circumstances.  My guess is
that you will be doing only a card swap and will be keeping your HPSUSAN
number.

Having just done this myself over the past two weeks I can offer you the
following headstart on vendor software that validates against both HPSUSAN
and HPCPUNAME, either one, or neither:

ORBiT           BACKUPPL                Both values
Bradmark        DBGENRL         Both values
Maestro         ROC                     Both values
ODBC/32 Minisoft                        HPSUSAN only
NetBase Quest                   Both values
SUPRTOOL        Robelle                 HPSUSAN only
OMNIDEX DISC                    Both values
SOS             Lund Perf Sys           Both values
MPEX, etc.      VESOFT          Both values
TRAX            Musicamusa              Neither value
