I just moved my sof2 server over to gameservers last night. I uploaded all my maps, added rocmod via gameservers console, downgraded rocmod to 2.0c, uploaded all my configs, did a couple settings changes, and then restarted my server. First time of a restart and everything works. Gameservers is the place to be.
There are many exploits to this old game, a big one is players being able to download your server cfg and take control of your server. This has happened to me many times. Remove your rconpassword and ask gameservers to nicely add your pass to your command line and you will never have to worry about that again.
Hope that helps some of you.
