Please read the “Upgrade Notes” sections of CHANGES.txt for the versions
between 7.3 and 8.2
It’s not necessary to upgrade ZooKeeper, but it is recommended if for no other
reason than SSL isn’t supported on ZK 3.4.x
You should be able to upgrade directly to 8.2, _assuming_ your index was never,
Hi all,
We have a 3 node solr cluster - version 7.3.0 using zookeeper -version
3.4.12, running on CentOS Linux release 7.6.1810. I would like to upgrade
to Solr version 8.2.
Is it necessary to upgrade zookeeper also?
Is it OK to upgrade directly to 8.2?
Any tips/checklist would be welcome.
Regard
