Migrating an account that had an ssl cert and dedicated ip address

Hi, This has not happened to me yet, but I am curious. If I attempted to restore a new customer's full backup from a previous host and: 1. The account had an ssl certificate 2. The account had a dedicated ip 3. The new server does NOT have any unused ip addresses When I attempt to restore the full back up, would it restore the account using the shared server ip address, and would the SSL certificated continue to work due to SNI (server name indication)? Would this throw any type of error? Thank you
