RE: 820-2395 to 820-2435 V5R1 or V5R2?

Mary Jo,

The minimum supported release for the #2435 processor is V5R1.  If your
friendly CE wants to install the MES and verify that your system works,
you must do an upgrade prior to his or her work.  Otherwise, you will
have the hardware installed and then power up directly into an upgrade.
Even that might not be possible (I'm ignorant here, you should be able
to IPL directly from CD following the hardware upgrade but it strikes me
as scary because you're increasing complexity and haven't verified that
the hardware upgrade was successful.)

Both V4R5 -> V5R1 and V4R5 -> V5R2 upgrades are supported.  As Alex
Moore suggested in his post, remember to read the documentation for both
upgrades so you're aware of all of the changes if you jump two releases.

What are the specific reasons for not upgrading the OS prior to the
hardware?  Could you just limp along with bad performance so that you
can verify the OS upgrade, then do the hardware?  Or is there something
which absolutely prohibits this upgrade?

My preference in your situation would be to find a way to upgrade the
software (your preference as to whether you go to V5R1 or V5R2, I would
go to V5R2).  Make sure the machine will boot and function, then have
the hardware upgrade done immediately.  All on the same weekend.

Andy Nolen-Parkhouse
