I don't recommend that you do this. I believe you can't do this at all if you are publishing to the web as Pro and Server will conflict.
We do routinely run Pro 10 and Server 10 here with no trouble, but this is a robot file that is launched late at night to run one script and then uses Exit Application to shut down Filemaker.
Running Pro (or Advanced ) on the same machine as Server could slow the machine down. Generally, running any additional apps on the server is not best practice as it (slightly) increases the change of problems for your clients of server due a crash being caused by the additional application.
