Re: [EXTERNAL] Cassandra 3.11.X upgrades

Manish is correct. Upgrade the Cassandra version of a single node only. If that node is behaving as expected (i.e. is in an Up/Normal state and no errors in the logs), then upgrade the Cassandra version for each node one at a time. Be sure to check that each node is running as expected. Once the C
