Subject Re: Upgrade using rebuild
Date Thu, 14 Dec 2017 11:08:53 GMT
If you want to do a version upgrade, you need to basically do follow node
by node:

0) stop repairs
1) make sure your sstables are at the latest version (nodetool
upgradesstables can do it)
2) stop cassandra
3) update cassandra software and update cassandra.yaml and cassandra-env.sh
files
4) start cassandra

After all nodes are up, run “nodetool upgradesstables” on each node to
update your sstables to the latest version.

Also please note that when you upgrade, you need to upgrade only between
compatible versions.

E.g. 2.2.x -> 3.0.x  but not 1.2 to 3.11

Cheers,
Hannu
