I'm wondering if Server 5.5 and 7 Advanced can reside on the same machine. We bought S7A for now, to host Cleveland Consulting's Multi-user Calendar, and it will eventually host our upgraded maintenance management system. In the meantime, our maintenance system is still in V6 hosted by Server 5.5.

The server in question is a brand new server with some very beefy specs. The multi user calendar is not a huge system and would have at most 20 concurrent users over IWP. But Server 5.5 would be hosting up to 80 concurrent users.

You can't use 5.5 and 7 servers on the same machine. They use the same port, which from what I've read, can't be changed.

I tried to run a sample database(s) on my server 5.5 machine and it will not run both 5.5 and Server 8 at the same time. I can turn either on but when one is running the other will not start! Darn..........

Same deal with Server 8: they use the same port.
