Migration from 10.3.1 to 10.3.1 won't work: SNI is not supported

[SacAutos]

I need to move an ecommerce website from one server to another. However, no matter what I try, I can't get it to go. Here's the error message that the migrator gives me:

Warning: phosting "website.com"
SNI is not supported. SSL certificate will not be restored on website.com

Error:
Failed deployment of client WebSite

(I've obviously changed the name of the domain to "website".) The domain is "owned" by a customer that has it and an email-only domain within it. There is also an error that follows about being unable to create the account because the email address already exists. I don't believe that's relevant to my main problem, as I've moved domains before with that error and the domain still deployed.

This is a big problem. Does anybody have any ideas on how to get around this? I've even tried disabling the secure certificate for the domain and moving it to a shared IP address and it STILL failed.

HELP!!

It turned out to be the customer that blocked it

Well, I've answered my own question. I was about to move the site manually when I had an idea to try moving the domains without moving the customer that owned them. That seemed to work. I recreated the customer info at the other end and reassigned the subscriptions to it. Annoying but it worked.
