To upgrade Chat Service 5.5
To upgrade Chat Service 5.5, just install Chat Service 5.5 Service Pack 1. If necessary, complete the steps under Preserving the Ownership of Persistent Channels.
Chat Service includes a service mode, SYSOPISOWNER, which grants owner status to chat sysops when they join a dynamic channel. However, this mode affects only dynamic channels on the server, not persistent channels. If you want SYSOPISOWNER set on all persistent channels, you must run the chatcmd /FixChannels option. If you do not run this option after you install Chat Service 5.5 Service Pack 1, SYSOPISOWNER will no longer be set on the server’s persistent channels.
