Move site and database to new server

I have two real estate websites that use a windows server and one MSSQL database which uploads info from and IDX database. I plan to move them to a Godaddy account. I know how to move most of the files but not sure of server side issues and coding on database codes that may need to be changed.? Prefer to have emails (3) also reset up. ? Also need an idea of what package I need from Godaddy for the sites. Prefer to work with someone Stateside or Canada. Could lead to more work later. Can view one of the sites here but not loading well at the moment which is why i am moving it. Server been dowmn most of two weeks. <[login to view URL]> ? sample database page <[login to view URL]> ## Deliverables I just want sites back up and running on new server with no errors and emails recieveing emails. DNS changes once checked out. and live sites working properly. ? Should be a pretty simple job.? Just need help on server side details and checks and balances.
