>finally thats what we r thinking of doing but concrned abt new runtime(.net framework) and hardware requirements this imposes . we've couple of hundred clients using our software and we need to convince them to upgrade their machines (incase they are using hardware not supported by .net)! Damn !!

We use the same hardware as it was before. On the server side, we run VFP and .NET applications. On the development PCs however, yes, I would recommend stronger machines.
