All, We are getting a lot of push back on the 3 stage process of going through the three compatibility modes to upgrade to Cassandra 5. This basically means 3 rolling restarts of a cluster, which will be difficult for some of our large multi DC clusters.
Having researched this, it looks like, if you are not going to create large TTL’s, it would be possible to go straight from C*4 to C*5 with SCM NONE. This seems to be the same as it would have been going from 4.0 -> 4.1 Is there any reason why this should not be done? Has anyone had experience of upgrading in this way? Thanks Paul Chandler
