Recently an EMR client called UltimatePc from Palm Desert, ca after years on inactivity (u know who you are):
They had a failing server, running PP-EMR
Needless to say, it was a touch and go situation. Not sure if the old server ( a Microsoft windows 2003 Dc) can be brought back to life. UltimatePc Network Engineers were able to not only bring the beast up, but also made the PP-EMR work again, without any major mishap.
I must stress that always backup, and also keep up on the technology, as you might regret loosing everything otherwise.
