How To Do the TMS Configuration?

We have two systems with version ECC 5.0
The SID is XY1 - Development & Quality
                 XY6 - Production
Now we need to configure TMS between these two systems by assigning XY1 as domain controller. I beleive we also need to establish an RFC Connection for this. Also explain how to update the local files of this systems?
