Awesome. One thing that has already happened is carlsguides.com is on the new server. I used that one to test the migration, and it went well. I was able to connect to the new IP within an hour, but people around the globe really could take up to 24h.
If this keeps going so well with other sites, I will just make the move, as literally everything else will work aside from the Forum, and some people will be lucky and get access really quickly.
Here is the address you will be able to access the Forum on when I have put us in maintenance mode and transferred the database:
http://104.130.66.63/forum/. When the new address is updated for you, you'll see the Forum out of maintenance and (hopefully) working as usual.
