Migrating samba users and settings from Centos 6 to Centos 7

There are lots of examples on the internet on how to migrate Linux/Samba users and Samba settings from one server to another. A few years ago I used one of those examples to migrate a Centos 5 server to a Centos 6 server with nary a hitch. I’ve been researching this topic for some time now and have come across very little information regarding this issue. In fact, a google search on this topic brings up a post of mine on LinuxQuestions as the first result.

How much Samba have samba changed? Is is possible that all I would have to do is change the Centos 6 UDI and GID to match the Centos 7 ones then follow the same procedure to migrate the accounts?
