Is there a way to perform a SnapMirror migration within the same controller without using the internal loopback adapter (~40Mbs).  I have a situation where I need to migrate close to 6TB of data (multiple volumes) off of older smaller drives to larger 300G drives. Ideally I'd like to use SnapMirror multiplexing, however, I'm not sure that, even with direct connection between interfaces, this would even work (I'm thinking that the internal loopback would still take over).  I don't want to do multiple snapmirrors (orig. controller> temp controller> orig. controller) but this may be my only path in order to get the speed that I need for the transfer.  Any ideas?
