In order to start the migration, start the Desktop Client and open the Management menu. You will find a new entry at the bottom "Start audit trail migration".

If the entry is missing, the user probably does not have the action right.

Only one migration job can run at a time, so if the menu entry is disabled, a job instance might already be running.

You can find the executed server job in the process overview perspective under System processes.

The problem log of the job will show the progress as well as errors.

The number of migrated changes is logged for every processed day. This includes also the number of errors or skipped changes. A change will be skipped if it could not be migrated, details will also be logged, or if its entity is not configured to support audit trail.
