You can register or unregister custom plug-ins from the Administrator Daemon.

You can make schema changes to custom entities with

prepare

and

upgrade

commands. Use the

prepare

command to generate a CSV file for a specific entity type with all the fields for all entities. You can add or edit the fields in this CSV file and then run the

upgrade

command to update the fields to the plug-in.

The

upgrade

command redeploys data flows that were deployed at the time of upgrade.
