I will be upgrading 4 indexers from 6.5.2 to 7.1.2. Will I need to stop all 4 indexers, upgrade them all, and then start them all again on the same version? Or can I stop indexer1, upgrade, start, and then do the same for the rest of the indexers? In other words, can 6.5.2 indexers co-exist with 7.1.2 indexers?
Thanks in advance.
