I think that a lot of my concern comes from the fact that my organization has no MCSE's in house, and our system's support staff has never professionally administered Oracle on NT, but yet has two qualified SA's in the Solaris world that have experience in Oracle on Solaris.

To me the dollar for dollar savings would be to remain on the initial platform (solaris) for the upgrade to 11i since there are no qualified NT professionals on staff to properly configure the server.

Someone made the point that MCSE's are a dime a dozen nowadays, but that doesn't make me feel confident that the Oracle Server will be properly maintained.
