Starting with v8.0.0 you can now shut down individual cluster nodes without shutting down the whole server. This command will use the SeeOtherHost strategy to direct traffic to other nodes and update the cluster map to gracefully shut down the single node
Shutting down individual nodes can be done VIA Ad-hoc command and fill out the response forms. The command is available from message-router as http://jabber.org/protocol/admin#shutdown.
