Migrating Membase Cluster – Part 2

After up all night babysitting the rebalance process, I am happy to report that it was a rather uneventful night of maintenance.  The rebalance itself took 8-9 hours to complete, and then took another hour for all the replicas to get saved to the disk also.  Theoretically, I didn’t need to take the site down […]
