Like Having an Easy Button

Granted, it might help that I was migrating from one SiteGround hosted site to another, but this went amazingly smoothly. I had used a self-owned domain to set up and test a new version of the WP site. When it came time to migrate, I backed up and deleted the old site, got the token, put the add-on on my test site, and 5 minutes later it was done. So far at least, seems like a perfect migration.
