Hi everyone, There were many people asking similar questions about the CASSANDRA-13004. It might be that the issue itself and release notes are somewhat hard to grasp or might sound ambiguous, so here's a bit more elaborate explanation what 13004 means in terms of the upgrade process, how it manifests and what exactly to do: https://gist.github.com/ifesdjeen/9cacb1ccd934374f707125d78f2fbcb6
If you're running 3.0+ Cassandra you might want to read it just in case. If you have any proposals in terms of how to modify/improve it, please ping me or comment on the gist, I'll make sure to adjust the text accordingly. Best regards -- Alex Petrov
