We are using Migrator 7.  However is this
normal for the code to be missing between migrations? Is there a way to
ensure/validate that the code really got to the destination?  I have
trusted the migration report – should I not trust the migration report? 



Is it normal for the migration to introduce new
bugs into production?



After the migrations we do not know what to
expect in production - I just do not see this as “normal”.  



The technical person says “well code can
be overlooked” (which is human) – however the report should be the
checkpoint correct?



Does
Remedy’ Migrator’s Source Control prevent these issues?



 



***************



You trusted Migrator to do all that?  I'm a
pretty religious man, but that



is beyond the limits of my faith.  Part of
using Migrator is knowing what it



can and cannot be trusted to do well.  It's
like driving an old car you've



owned for a while - you know it's weaknesses and
limits, and you learn to



work around them to get where you're going
without incident.



 



I have run Migrator on systems with similar or
less system resources, so I



don't think that's the problem.



 



My first guess was that either the person using
Migrator didn't fully



understand exactly what it would do (who does?)
or didn't have it configured



exactly as it should have been, which is pretty
common.  But then you said



that the Migration took 25 hours?  I have
never seen Migrator take anywhere



near that much time to do what it does, even
with massive changes to



migrate.  What version of Migrator are you
using?  The newest one is



supposed to address some performance issues, but
that doesn't address the



data corruption issue, which is the more serious
one, IMO.
