Trying to migrate our environment to the cloud, registration server isn't allowing us to use our license on the new machine.

We are a long standing customer, in the process of migrating our
environment to cloud servers. We need pushok running there, but it won't
take our licenses. Need help getting properly generated license (when I
try to apply our current one it says we need UNIX 1.x package, which isn't
on our license, although it should be).
