["Paulo Motta (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-19243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paulo Motta updated CASSANDRA-19243:
------------------------------------
    Description: 
This is an umbrella ticket to discuss removing pre-4.0 compatibility code from 5.0, similar to CASSANDRA-12716 for 4.x.

A few considerations:
- Discuss/ratify removal of pre-compatibility code on dev mailing list
- What compatibility features are being removed?
- What upgrade tests are being removed ? Are they still relevant and can be reused?
- Should upgrade from 3.x to 5.X fail on startup with an override flag?
- Can/should we make it easier to deprecate/remove compatibility code for future major releases?

  was:TBD
