Rance Smith commented on CASSANDRA-11292:
-----------------------------------------
I played with this more and was able to get it upgraded by going from 2.1.9 ->
2.2.5 -> 3.3
FYI this DB did start with version 2.1.9 originally.
> upgrade from 2.1.9 to 3.3 getting Nulllpointerexception "Exception
> encountered during startup"
