So I decided that it wouldn’t be a bad idea to really get at the guts of MOSS and figure out just how PSConfig works and what the different application pools are useful for.
So the first lesson learned of the day is that the web application for Office Server really should never be toyed – if you delete it you might as well just reinstall MOSS all together 
Second lesson learned of the day, there is no real good way of migrating MOSS from one SQL server to another without rebuilding the server’s MOSS instance and then reattaching the content databases and if you’re lucky, getting the SSP’s in as well.
Any other lessons learned out there that anyone else would like to share?
