Last year we did a migration of a government system using exactly that mix
of software off a VAX 7400 to Windows 2003 in about a month.  Now anyone
will tell you that Windows is not my favorite platform, but the customer
claimed to want it, so we did it.  It took about a month to resolve their
source code control issues, and another month to write bits and pieces that
are standard in VMS but missing from Windows.  But the actual application
migration only took a month.  It has been absolutely rock solid ever since.
The ABF code compiled without a single incident that I can remember (apart
from idiot mistakes of my own).

Incidentally, what made the migration all the more remarkable, was that we
moved the ABF applications off the server onto the client workstations
because Windows doesn't have a usable telnet server.  I give ABF all the
credit for the ease with which that was accomplished!

If we could move from VMS to Windows that easily, it shouldn't be all that
hard to move to anything that is stable.  So your real problem is more about
how stable your intended target platform is.

Ah QUEL.  Happy days...
