AS/400 upgrade to v5r2

We are migrating to version 5.2 from version 4.5. We are BPCS 6.04; apr cum; 
heavily modified.

Any issues upgrading to V5r2?? Thanks in advance.

Here is what I know for upgrading to version v5r1:


1. Test on upgrade: queries and FORMS. See this web site; pay particular 
attention to APAR#: II12963:  Try 
http://www-912.ibm.com/supporthome.nsf/document/20300257.  Select "Search 
Software Problems (APARS)" from the first box w/ drop down arrow; hit go.  From 
the next screen, put in BPCS as the search criteria.  Hope this works out.

2. Everyone who upgrades to V5R1 and has BPCS V6 or V8 must read IBM's Info 
APAR II12963 for running BPCS on the AS/400, and then order and install those 
recommended PTFs. There are some which have special instructions to follow. 
There is a notice in the Product Bulletins section of OGS Online which mentions 
further details about this Info APAR. It is very important to do this, or you 
will most definitely have BPCS program errors. However, I have not heard of any 
issue with data integrity problems at the database level. Many of our systems 
at SSA GT have been updated to V5R1 and we did not experience the issue you 
describe. Genyphyr Novak SSA Global Technologies

3. > Alma Did you install CUM package C1114510 or later?  Ensure that you do  
if you have not already done so.   There is also a database group PTF that you 
should get as well.   This database group ptf deals  with temporary objects 
building up and eventually crashing the iSeries.  I do not remember the precise 
name of the database group  PTF but it is included with group PTF SF99146 for 
Websphere.   Andrew From alma: Did anyone encounter any data problems such as 
data  being shifted to right by 7 bytes or so, thus  producing unreadable info? 
 This started to happen  after our OS upgrade to V5R1.  We also installed the  
required PTF to address the enhancements done to some  SQL commands.  Any 
guidance will be very appreciated.

4. EDI package extol needs to be upgraded:Release V5R1 of the OS/400 operating 
system contains many new features, functions, and other marked changes over 
prior releases.  One feature, "Increase library list for an active job", 
expands the number of libraries supported in the user portion of the library 
list from 25 to 250, and requires some adjustments on the part of most packaged 
software applications, EXTOL included.  Support for OS/400 V5R1 is included in 
the current cumulative PTF package for EXTOL Integrator Release 5.5.  If you 
are planning to upgrade to OS/400 V5R1, contact EXTOL customer support at 
800-542-7284 with the date planned for the upgrade, and the current CD will be 
sent.

5. IBM APAR's need to be evaluated, especially: APAR#: II12963  Component:
