Yes the KB accurate , in what you need to do.i.e applied to 3.6 too
While it mentions rebooting the servers after moving users,handheldcleanup does the job ,since you may not be moving all the users at the same time ,risking multi boots.
handheldcleanup work for mailbox moves from one server to other
rebooting the server is required if mailbox is moved from one store to another on the same server
