What order do you shut down all GIR stuff?

Hey guys if you need to shut down all of GIR, for something like an OS patch or VM host move, what order do you bring things down in and what do you leave running?  Was thinking some things like Apache/RWS could just keep running along, but not sure about Cassandra.

I always shut down the WebDAV and RPS as first to make sure the recording will not be lost during the maintenance (MCP will store them locally while the WebDAV and RPS are not available). DUring startup, the WebDAV and RPS is started as last.
