Upgrade strategies

How did you evaluate the upgrade from PDMWorks Enterprise2007 to 2008? The only solutions I have found are a pain in theneck!

I cannot have a 2007 and 2008 vault view on the same machine. Icannot have PDMWorks Enterprise 2007 database and archive serverrunning on the same machine. Has anyone found a better way thansetting up a completely different server with completely differentclient machines? It is so time consuming and difficult to scroungeup enough computers! Let alone enough time to get some guys on itto try and break it.
