Hi All, I've successfully upgraded a 2.0 cluster to 2.1 on the way to upgrade to 3.11 (hopefully 3.11.4 if it'd be released very soon).
I have 2 small questions: 1. Currently the Datastax clients are enforcing Protocol Version 2 to prevent mixed cluster issues. Do I need now to enforce Protocol Version 3 while upgrading from 2.1 to 3.11 or can I still use Protocol Version 2? 2. After the upgrade, I found that system table NodeIdInfo has not been upgraded, i.e. I still see it in *-jb-* convention. Does this mean that this table is obsolete and can be removed? Thanks!
