Migrating file server data to new server

We are in the process of upgrading our file and print server to a newer, more robust machine. This is a whole new process to me and I’m wondering what things I need to be aware of when it comes to migrating the data to the new machine. I’ve foundinformation regarding a printer migrator tool on microsoft’s site, but otherwise haven’t been able to locate much other info regarding this process. If anyone could point me to some good info it would be most appreciated. Both the old and the new machine are Win2k Server.
