This article by Jack Downing and Michael Herring describes how to use the Sametime System Console to configure your 8.5.1 Sametime servers with an 8.0.2 Community server.
The article is also a good ressource when you have to troubleshoot a community server installation, because it describes some configuration files that are worth looking into.
The link to the article does not display, ti gives me an HTTP 404 error. I searched for the entry in the WIKI but it did not come up – could it have been moved?
Victor: The article is no longer in the wiki. WTF. Not sure what is going on at the moment. PlanetLotus, Ben Rose quit the OpenNTF Teammailbox project, article is removed from the wiki .. What comes next?
