Snapmirroring from a snapmirror destination

Has anyone  used a snapmirror destination as the source for another snapmirror going to another destination.   An example would be Volume A is being snapmirrored from Site A to Site B.  Volume A on Site B is then being snapmirrored to Site C.  This is being done because the bandwidth at Site A  is limited and we do not want to run a Snapmirror from Site A  to Site B  and Site A to Site C.    I have not found to much information on this.  The snapmirrors use the same volume signatures with different time stamps.  Normally you would have 2 different volume signatures snapmirroring from a single site to 2 separate locations.  It works but it makes me uncomfortable doing it.

Completely supported. The technical term is cascading SnapMirror.

This can be done through the CLI.  It can't be done through the QUI.  Also only 2 hops as you have described is supported.  So the easiest way would be to snapmirror A to B through system manager.  Then use the snapmirror create command from location C.
