Is it possible to migrate an sbs2011 to exhange365 if the domain is controlled by dynamicdns.org?
because i my self has no static ip-address.
As long as you have a proper certificate from an official CA, so not self-signed, I don't see a problem. As long as O365 can find your server at the FQDN you should be able to migrate.
Thank you for the quick answer.
