The command above will trigger the install of the new Cassandra version. You can follow the upgrade progress by making a REST request identical to the one used to follow the progress of a [configuration upgrade](/1.7/usage/service-guides/cassandra/configuration/).

**Note:** The upgrade process will cause all of your Cassandra node processes to restart.

**If you are upgrading to or beyond 1.0.13-X.Y.Z of DC/OS Apache Cassandra from an older version (pre `1.0.13-X.Y.Z`), here is the upgrade path:**

1. Perform [Backup Operation](https://github.com/mesosphere/dcos-cassandra-service#backup) on your currently running Cassandra Service. Please make a note of the backup name and backup location.

4. Once the restore operation is finished, check if the data is restored correctly.

I think this should be up at line 302. This is more important than the section on the special upgrade path.

* The upgrade process will cause all of your Cassandra node processes to restart.
* Upgrades are supported from version `N` to `N + 1`. So, if you are on version `N` and want to get to version `N + 2`, please upgrade from version `N` to `N + 1` first, followed by an upgrade from `N + 1` to `N + 2`.
* Upgrade from `1.0.15-3.0.7` to `1.0.16-3.0.8` is not supported.

Currently, 1.0.15 to 1.0.15+ is unsupported.

Can they still perform the backup/restore upgrade? Saying 'not supported' implies that's also not possible.
