Hi All, This is now completed.
Overall time spent was around 3 hours on the Operations Center and 5 masters. When the OC was being upgraded, there was no downtime for the masters. Each master had downtime of around 20 minutes to 30 minutes, including multiple restarts , backups and plugin upgrades. CouchDB folks - most of your nodes are connected via 'node connects to the master' meaning that you'll have to update each slave.jar manually. The preferred method is ssh i/o non-blocking, all nodes connected in this fashion all came back on their own without intervention.
