Chapter 2. Migrating business processes to the new process designer
The legacy process designer in Business Central is deprecated in Red Hat Decision Manager 7.8.0. It will be removed in a future Red Hat Decision Manager release. The legacy process designer will not receive any new enhancements or features. If you intend to use the new process designer, start migrating your processes to the new designer. Create all new processes in the new process designer.
The process engine will continue to support the execution and deployment of business processes generated with the legacy designer in to the KIE Server. If you have a legacy business process that is functioning and that you do not intend to change, it is not mandatory to migrate to the new designer at this time.
You can only migrate business processes that contain supported business process nodes in the new designer. More nodes will be added in future versions of Red Hat Decision Manager.
To enable or disable the legacy process designer in Business Central, in the upper-right corner of the window click Settings

If the migration is unsuccessful due to an unsupported node type, Business Central displays the following error message:
