I have converted an application from many machines to
other lines.

I started out on the VAX (in my opinion the best
machine still to this day), then to HP3000, then UNIX
(HP, SUN, IBM, DG, etc) then to Powerhouse NT.

I created a system management module that takes all of
the O/S level code away from your application. This
allows me to convert from one platform to another
transparently to the User/Application.

The problems you are going to encounter are:
1) Quiz does not run in compiled form (at least it
didn't work correctly at the time of implementation).
Not a big problem since every user has their own CPU,
they do not notice.
2) There is no real Batch Queue. Everything is run
interactively. I didn't have time to create one and
the client didn't care as the performance was 10 times
faster.
3) Printing is a little more difficult to set up. The
printers have to be set up on the network server. My
system management module took care of this, but the
testing was a bitch.
4) I used strictly Powerhouse, no COBOL, etc. That may
be a problem for you, depends on what you are doing in
there.

Hope this helps.
