Audit logs & camunda (zeebe engine) version update

Hello All,

Could you please help me regarding the following cases? To clarify the facts.

  • Audit logs: Is it neccessary to export the audit logs via exporters? Or can it be write out to stdout?
  • Updates: What happens with the stored processes in the event of camunda (zeebe engine) version update? How invisible such an update from the point of view of “process executions”?
  • Updates2: Should we pay attention for anything especially when installing a new process app version? How visible/invisible is such an update?

Thank you for your help.
