The larger part of server tree maintenance has been obsoleted by the new SQL-based model. At the time of writing, all database updates are handled through the Apache server, so Apache should never need to shut down. Likewise, all cadmin commands are executed through the Apache server. We have not yet tested performing database updates while clients are actively connected; please test this functionality with care.

You need to run cadmin scan_channel with the proper channel labels when your server trees change. Most people set this up as part of the cron job that updates the trees on the server. This is the only maintenance that Current 1.6 needs.
