RE: V4R5 upgrade to V5R1

["Mark A. Manske" <mmanske@xxxxxxxxxxxxxxxxxx>]

The upgrade book that comes with your software has a fairly decent
calculator,
follow that; IBM usually pads well enough.

We did the same to an 820 here - slow tape backup, but started at 8am on
Saturday,
was done at 10pm on Saturday - many, many factors play into the length of
time,
how much memory, dasd, files (physical and logical), interactive and batch
cpw,
and how much you pay attention to switching cd's (I know one person that
forgot
to check, and it sat for two hours).

I know this is an off the wall question and a lot of factors weigh into
this, but thought someone may have a ballpark idea. We need to plan
upgrading from V4R5 to V5R1. How long should we expect this to take,
"assuming all goes well"? If we can not take our system down until 6pm on a
Saturday, when can we hope to be finished - Sunday sometime or would it take
longer? Basically looking at whether we can do it during a "normal" weekend
or whether it should be an extended one. We are on an 820.
Thanks.
Dave
