Hi all,

I am doing some testing of Cassandra 6, in particular the upgrade path at the 
moment.

I notice in the cassandra.yaml and the cassandra_latest.yaml the majority of 
the text references CASSANDRA_4 still, with only one reference to CASSANDRA_X.

I have tried it with CASSANDRA_5 and that works as expected, writing C*5 oa 
sstables. I also tested it using CASSANDRA_4, and that seemed to work too, 
writing C*4 sstables and then upgrading to C*6 when the 
storage_compatibility_mode is set to UPGRADING. 

So my question: Is 4.0/4.1 -> 6.0 a recommended upgrade path these days? As far 
as I know it has always been recommended to upgrade to the next major version, 
not to skip one.

If that is not the case and the upgrade path should only be 5.0 -> 6.0 then I 
am happy to create a Jira and PR to fix the cassandra.yaml and 
cassandra_latest.yaml

Thanks 

Paul
