Hi All We were evaluating the upgrades of Cassandra clusters managed by us to Cassandra 5.0. It's clear that Cassandra 4.0 to Cassandra 5.0 is supported. But I am not sure what is the status with respect to upgrading Cassandra 3.x to Cassandra 5.0.
Some online resources I found say it is not possible and you should first jump to Cassandra 4.x. Following resources talk about the upgrade path 1. https://planetcassandra.org/news/top-5-questions-we-re-asked-about-apache-cassandra-r-5-0/ 2. https://www.instaclustr.com/blog/top-5-questions-were-asked-about-apache-cassandra-5-0/ Also Cassandra 5.0 announcement says, "Upgrading from 4.x to 5.0 has been designed and tested as an online upgrade, minimizing downtime for your applications." Here is the link <https://cassandra.apache.org/_/blog/Apache-Cassandra-5.0-Announcement.html> . Meanwhile there is a slack discussion <https://the-asf.slack.com/archives/CJZLTM05A/p1726630791029329> based on which my understanding is that there should not be an issue for upgrading to Cassandra 5.0 from Cassandra 3.x. I tried upgrading path (3.11.12- -> 5.0.0) using ccm but ccm seems to not allow me to change the JAVA version on one node and is picking the JAVA_HOME set on the machine. It would be of great help if somebody could confirm if Cassandra upgrade from 3.11.x to 5.0.0 is supported or not? Regards Manish
