How to Change a MOSS Server to a Different Farm and Configuration Database

OK, big disclaimer on this one. I didn't RTFM. But this is what I did to reconfigure our large farms (6 web/query servers plus two indexers).

If you just went to a server and ran the Configuration Wizard, you would find that you cannot switch configuration databases. If you went into Central Admin (even if it is running on another server) there is a Remove Server link. If you click it, it tells you not to do it that way. Listen to what the box is saying - do not do that. Do what I say below!

The first thing to do is run Add/Remove Programs, select Microsoft Office Sharepoint Server 2007, Change, Repair. At the end of the repair it needs a reboot.

Then you rerun the Configuration Wizard and it may know you were trying to "repair." If not (I have seen inconsistency on this), go back to Central admin and remove the server (this time answer yes). If it was still connected to a config database, exit and restart the wizard after removing the server from the farm at the ../_admin/FarmServers.aspx page. Back in the Configuration Wizard, it will now bark that it can't tell if the server is in a farm (although it seems to know that it once was). This is actually a good sign. OK that BIG message box, and then you have no choice except to disconnect from the farm. This seems to clear out any remaining settings regarding the farm. Good stuff.

Then (I think you can guess this), you rerun the Configuration Wizard. Now it is like the first time you ran it on a freshly installed server. You can connect to another config database and it will run the full range of tasks (this whole process is one of the cooler administrative things I have ever seen - I wish the rest of the software was as cool!). It syncs up all your installed features and stuff. You are done, and ready to give this server a role in your farm.

    Got here because I had an error after repairing one of my MOSS Servers. It seems running the config wizard again is very important.
