Hello everyone, a general question on cluster upgrade from very old to new. I am running version 2.10.1 currently and planning to upgrade it to 4 then 5. My security team has highlighted few critical CVE which are fixed in 2.10.6 and I have to upgrade the cluster. Question is, can I directly upgrade cluster from 2.10.1 to 2.10.6 or I have to hop every patch version in between ? Once its on 2.10.6 I will move it to 2.11 then 3 and 4. TIA 🙏

you can jump from 2.10.1 -> 2.11.x -> 3.0.x -> 4.0.x

got it thank you @merlimat, Is rollback also possible in same manner if in case I land into some issue ? for instance if upgrade (2.10.1 -> 2.11.6) fails at any level can I rollback to 2.10.1 ?

Yes, if you don’t change any enable any new feature from the new version, you can always roll back to the previous
