How to parse old apache logs - error.log.1, error.log.2.gz?

Are those re-parsed by default after adding new collection/scenario?
And what about after updating one and reload-ing crowdsec?
If not - how to force a re-parse of all logs?

Hello,

Log are only process one time.
If you want to replay them, crowdsec provide a replay mode: Replay Mode | CrowdSec
