Moving IT infrastructure

One of the things I get to plan is moving the IT infrastructure. Pulling the plugs and moving the servers is the easy part; but what about the DSL, static IP, mail, MX records, DNS..

I think I’ve found a solution for the mail (hosting the mail server) and the DNS is already moved out and re-hosted on two different DNS servers. Might be just web-mail for a week or so – but that’s more than enough.

The blogs and photos will be offline while the servers are on the move – the rest of the infrastructure is just internal stuff; NAS, print, authentication etc.

Any hints and tips from those that have moved SLES and Windows 2003 servers before?
