How to run rehostuser such that imsbackup gets piped directly to imsrestore without having to go thru ssh?

Note: unless you are doing something exactly like the scenario described here, you should NOT use this article.


In this very specific scenario, both instances are running in a cluster and will be running on the same host during the move. Therefore, since it is all on the same system, having rehostuser invoke imsbackup, pipe to ssh, TCP connection to remote sshd, pipe to imsrestore; involves a few wasted steps. For the amount of data being moved in this specific case (millions of users on dozens of systems), that could add a considerable amount of time to the moves.

If you are trying to move a user from one partition to another within the same message store instance, DO NOT use rehostuser user, just use mboxutil -r.
