Database connection configs / making 4 ASP sites work

I have recently moved 4 ASP sites (1 classic ASP, the others various versions of ASP.net) to a new server.
The files are moved and so too are the databases, so it's really just a case of setting the correct database connection strings and making sure the sites are working and not throwing any errors.
I can provide control panel, db and ftp access, so you will have all the information you need.
Please contact me with a rough idea of how long that will take, and/or further information if needed.
