Currently, there is a Webadmin API for upgrading Cassandra schema version to a specific version.].
However, the admin is unable to retrieve all available Cassandra schema versions to determine which version he should perform an update to. He might need to check directly in the James database which is quite complicated and wasted more time.
Thus, as a James Ops, I would like to request a Webadmin API for retrieving all available Cassandra schema versions.
