Re: Sys/36 virtual machine, or OS/400?

[Jerome Draper <jdraper@xxxxxxx>]

Why wouldn't you just move directly to OS400 based apps from the *M36.  So
you can migrate slowly over time?  I am working with a client who moved
from a 5363 to a M170 in *M36 and (really funny) a job that previously took
3 hours ran in 3 minutes.  We thought it was broken and searched for the
failure point for hours only to determine that all was well.  Users think
we are great.
