I'm very pleased with Interserver's site migration service. It took a little bit of time to get on the same page, but once we were the service was done within the 48-hour time frame as promised.
Everything (WordPress installs sub directories, subdomains, url redirections, etc) have been copied over perfectly.
I just turned off my auto-renew for The Ice Cave with HostGator. And I closed out my web.com account.
