Re: new serial with V7R1?

[Dan <drothman@xxxxxxxxxx>]

Glenn, is your question "what release can I run on which server?" or 
"how do I upgrade and preserve my serial number?"

Some things that might help you:

1. IBM maintains a web page which shows which Power and System i models 
work with which releases of IBM i:
http://www-947.ibm.com/systems/support/i/planning/upgrade/osmapping.html

2. As Larry pointed out, IBM doesn't offer an upgrade from POWER5 
directly to POWER7.  There are some upgrade paths from POWER5 to POWER6 
(from which you can upgrade to POWER7) but I believe that these upgrades 
will be withdrawn from marketing May 27, 2011.

3. Going back to Jerry's original question, I wonder if what someone 
said was that since upgrades from POWER5 to POWER6 go away May 27, in 
June or later you can't two-step upgrade a POWER5 box to POWER7 and keep 
your serial number.  Maybe "POWER7" and "IBM i version 7" got confused 
in someone's memory.  Or maybe it's me that's confused.  Happens all the 
time.

4. If you don't care about preserving your server's serial number, you 
can replace your POWER5+ server with a new POWER7 server running IBM i 
6.1 or 7.1 now, or in June, or whenever you like.
