From versions 2.11.x

If logs are collected in the cluster (client, management), then before starting the update to 2.13.x, disable Local log collection module (Vector) (shturval-log-collector).

Logs collected before the cluster update and placed in the log storage component VLogs, will remain available after the update.

To do this, after the update is complete, re-enable Local log collection module (Vector) (shturval-log-collector).
