Re: V5R4 to V7R1 question

Jon,

Well, that would depend on the route he decides to take for his upgrade. 
 If he's going to upgrade his old box to 7.1 before transferring -- 
then I would recommend going to 7.1 first on the old box, then move that 
to the new box, then upgrade the new box from 7.1 to 7.3.  Depending on 
the window of downtime allowed, this might not be feasible to do all at 
once, and may have to be split across multiple "windows."

Going to 7.3 on his old box will almost certainly not work, as the old 
box probably doesn't support a release that new.  And IBM doesn't 
support a direct data migration from 5.4 to 7.3, anyway.  (Another 
problem with waiting this long!)

If he decides to just save his user libraries and restore them on the 
new box, then then he might as well skip 7.1 and 7.2 completely and just 
restore straight onto a 7.3 box. This is one of the tradeoffs of going 
through all the pain of reconfiguring all your settings -- you don't 
need a migration path that IBM blesses :-)

But you're absolutely right...  if you're going to go through the work 
of upgrading, you might as well go to the latest and greatest.  If you 
can pick between 7.3 and 7.1 there's absolutely no advantage or value to 
picking 7.1.  7.3 has everything that 7.1 had, plus more, and no down 
sides that I've seen.
