To support products for 22 years is difficult.
Using VMware is a good solution that we have been using for a long time.
I even use Win2000 pro for some applications and Dos all under VMWare.
The connection to the Linux file system is "samba".  

Everyone misses the point.  The problem is setting up a system the way
we want it and the ability to do that after RH 7 is broken! and has some
land mines.  A function that can wipe out a file system is flawed and
cannot be trusted. 

Fortunately VMware works - we just bought a new VMWare version.  Update
is painless.

There is a big mismatch between Scientific Linux 6.3 to Redhat 7.9 in terms of libraries, file structure and type of libraries between the software and we have not been able to reconcile those.
