It's a work place and said company uses their IT staffers to provide transition from old to new systems.
If not, it's time to replace the old (unnamed) apps.
There is one method that works great. In a rare fit of showing "We can do this" I used RussinovichDisk2VHD app to create a ready to run Virtual Hard Drive and Microsoft's Virtual PC to run the old system in Microsoft's Virtual PC.
Any decent IT staffer knows this area so make them earn their pay.
