We are running GroupWise 7 on a Windows 2003 server and we wanted to test GW Messenger. I was thinking of installing it on a different server so if we need to reboot, or whatever, we won't be affecting people who are using GroupWise. People here are upset when email is unavailable even for a short period of time.

Here's my question... I'm assuming I will need to install eDirectory on the server and I'm assuming it will need to be the same version as the eDir on our GroupWise server, correct? Also, if we do decide to install Messenger on our GroupWise server, does Messenger use much resources? Our GroupWise server is running on a VM and I don't want to overtax that VM.
