Regardless of the fact that OLE DB is being deprecated, we need a fairly robust SQL Server to handle a lot of requests (not HealthCare.gov quantity, but within our company with hundreds of users). We plan only to use FoxPro data via a linked server only in the interim while we port the entire thing completely to SQL Server.

Yes, I think it would be possible to re-install a 64 bit SQL Server after the conversion is complete.
Yes, I'm wondering about that myself. Will a SQL backup made in a 32 bit SQL be compatible with a 64 SQL?
