Hello, I have a running Apache Cassandra 3.11.6 cluster of 7 nodes.
I had upgraded to 3.11.6 version from 2.1.9 version. After upgrading I ran `nodetool upgradesstables` on all nodes at once. And see that it got completed and data present in data directory has been converted to 3.11.6 format.
Now I am not sure whether I should run `nodetool repair -pr <keyspace>` on all the nodes, starting with rest of the nodes and coming to seed node at the end. Could anyone please guide me the best practices?
