Although the server and client versions are different, the problem?

hi

I was upgraded to version 12.1.5 in the SEPM 12.1.2 version

So I use the current version of SEPM 12.1.5.

but SEP uses the 12.1.2 version.

Is there are different versions of SEP and SEPM a problem?

and Should a problem occur when i use the SNAC?

I need your help.
