I am planning to upgrade my 6 node Apache Cassandra from 3.0 (RHEL 7.9) to 4.1 version (RHEL 8) without downtime. We are moving to new RHEL 8 server. We are upgrading with 4.1 version on the new RHEL 8 server. Please help us how can I do it without a downtime.
- Can we move the data prior to the upgrade window and just start the cassandra 4.1 in RHEL 8 during the window?
- What is the best way to copy the data? Export/Import or SSTableloader
Please advise. Thanks in advance.
