Re: AS/400 V4R2-R1 "downgrade"

[Chuck Lewis <CLEWIS@xxxxxxxxxx>]

Did you folks just go ahead and try this or did SSA give you their blessing ?

My previous employer has been told different stories. The last being that they 
would NOT support our current version of BPCS on
V4R2 or V4R3 (I think depening on which day you spoke to them). I ran into the 
SAME thing when we moved from CISC to RISC several
years back. APPARENTLY we were one of the early ones to do this and I can't 
BELIEVE the rigamaroll (sp ?) that we had to go
through. We EVENTUALLY got what we needed but the "alliance partners" seemed to 
be more on the ball than SSA...
