You can also do two transition snapmirrors from the source (one to the new source and one to the new destination)

They talk about transitioning the target from the existing snapmirror, however this is going to work in my environment, I think. 

Based on this doc, I think I will need to do a complete sync during the outage window. 

Thanks :)

I am trying to migrate a replicated volume to CDOT, but I can't use 7mtt. My plan is to set up a transition snapmirror and do the cutover manually. I can't start the regular snapmirror of the CDOT transition snapmirror target, though. I get "Using a transition volume as a snapmirror source volume is not supported". 

I have a long outage window, but would prefer to pre-seed the mirror of the new volume. What would you folks suggest?
