Marking as QA/Blocked pending question sent to @tmancey

Want to confirm that the test plan only applies to logs going forward, not backward.

[tmancey]

This PR only applies to logs going forward as there is another PR from @NejcZdovc which will remove/disable logging which will now remove all legacy logs
