Yeah we've had enough downtimes.
* I'll move over all the data (actual files, database, mail accounts etc) and check so that it's working on the new server.
* Then I'll put the forums offline here, make a database backup and transfer that over to the new server (should take about 15 minutes, both servers are on 100Mbit/s connections)
* Then import the database on the new server and enable the forums on the new server as well.
* Then make the DNS changes for the domain and people will pop up at the new server once their DNS resolves (will be anything from 5 minutes to 24 hours depending on ISP)
* And finally I'll be posting a little message on the old site that the forum has been moved to a new server with directions on how they can change their hosts file to access the new server immediately.
Easy
