RE: upgrading from 720 to i520



fixed

Rob,

You are correct.

"RISC-to-RISC" is the term IBM uses for a side by side upgrade, where you have 
the new server sitting next to the old server.  There used to be a book, 
"iSeries 940x RISC-to-RISC Road Map, SA41-5155" but now the information is 
located in everybody's favorite place, the Infocenter underneath "Migration".  
Try this link: 
http://publib.boulder.ibm.com/infocenter/iseries/v5r3/topic/rzamc/rzamc1.htm

In addition, as Jim mentions the recommendation in both the old book and the 
infocenter is to upgrade your old server to the release you new server is on.  

HTH,
Charles Wilt

Several people do successfully save items off a V5R1 machine on to a V5R3 
machine.  With the claim that it saved them downtime because they didn't have 
to take the time to upgrade the V5R1 machine to V5R3.  I'd argue that I've seen 
TOO many problems with this technique.  LPP's messed up, IFS objects messed up, 
user profiles, authorization lists, object authorities, directory entries, 
system values, etc, that I would not recommend this method.  I'd argue that it 
will actually increase your downtime fixing all the mistakes.

Judging by the earlier response, perhaps that is what is meant by a 
RISC-to-RISC upgrade.  And I wonder if that recommends upgrading the OS first.

Re: upgrading from 720 to i520






In the question, the i520 is already at V5R3. So the first part of  D 
would be right? am I right?
When you add the second part ("Upgrade 520 to OS/400 V5R3"), it makes it 
wrong.

So what would we be missing to save objects on the 720 at V5R1 and 
restoring only what is needed to a brand new i520 running V5R3.
