This cluster was running IPv6-only (still is) and thus I had the flexibility of new IPs. First I temporarily moved the MONs from hardware to Virtual. MONMAP went from 3 to 5 MONs. Then I moved the MONs one by one to the new DC and then removed the 2 additional VMs. Then I set the 'noout' flag and moved the OSD nodes one by one. These datacenters were located very close thus each node could be moved within 20 minutes. Wait for recovery to finish and then move the next node. Keep in mind that there is/might be additional latency between the two datacenters.
