I think instructions for migrating a server shiuld be added. And especially, it should cover things like how not to make your domains names point to each other, because I had the issue that my domain names pointed to each other so when someone went to one of my sites they could see another one of my sites, and this happened during the migration. The support staff could not figure this out, and I was scared to migrate. Howvever, I was able to figure out what caused the issue by myself. And as it turns out the site IP will point to a defualt domain, and this will cause your other domain names to point to the IP leading them to that default domain during the migration, especially during the progagation period after DNS settings are changed. This will cause customers to go to the wrong sites. Also, how to uninstall a CDN before migration should be added to these instructions, because that caused my site to break. Also it should be mentioned that on your new server backups are not made by default.
