Hi Petrus, Thanks! I see it's considered a good practice to always have snapshots, but I couldn't quite understand if it is possible to add new nodes running Cassandra 3.11 into a Cassandra 3.9 cluster. I tried doing so this morning, using `-Dcassandra.force_3_0_protocol_version=true`, and everything worked fine, but these new nodes were with 90%+ of cpu usage, so I removed them. Do you have any idea why this happened? Should I always upgrade every machine locally, keeping its data, instead of adding new nodes with a newer version? Best,
