Yeah, I saw your thread, the problem is more complicated due to size of the cluster... I'm trying to figure out the best solution, which will minimize the downtime and migration time.

I guess RBD mirror seems the was to go. Build a Cluster on the NEW Site and configure mirroring. Another idea is to Stop your origin Cluster, rent a car, Transport it the new location and Start - hopefully - All again At the new Site. Just my 2 Cents Mehmet Am 19.
