I have just embarked on the scary process of domain transfer. It feels like i'm in a black hole, a no-man's land between registrars. At some undermined point my hope is that it will have occurred without hitch when I can again tell the world where my sites are hosted. I think the process would be more reassuring if instead of having to cancel in one place and order in another (the very thing that is creating this anxiety and post) they changed it to order in new place and ask old place to send requester a release code. I'm sure it will be ok but to me it is like selling your house and having to wait a few days before moving into the new one, tbh I would be far happier with that scenario but I think you get the gist.
