Connection Manager 2014 with previous versions

SOLVED

I have a user who would like to install sage 50 2014, however we have a user already on 2013, and the 2013 connection manager installed.

If I upgrade connection manager to 2014, will the 2013 user still be able to connect to his 2013 databases, or do I need to upgrade him to 2014 as well?

Thanks!
