Freepbx migration

We currently have an instance of Freepbx 1.8.11 and are now installing a new instance of Freepbx 12.

We would like to migrate the call history from the old instance to the Freepbx12 instance. How do we go about doing this?

Thanks.

You can export the CDR database from the old PBX and import it to the new PBX. Search on mysql dump for the commands. If you have the Master.csv of the CDR you can move that over as a backup.
