Chapter 2. Migrating business processes from new to legacy process designer
You can migrate a business process from the new process designer in Business Central to the legacy process designer. By default, all business processes open in the new process designer. But once you migrate a business process, it will always open in the legacy designer.
Migrating business processes is an irreversible process.
Procedure
- Log in to Business Central and go to Menu → Projects.
- From Assets tab, select the business process. It will open in the new process designer.
- Click Migrate and a warning will appear.
Click Migrate Diagram.
The process designer will restart and the business process will re-open in the legacy process designer.
Migrating a business process will result in two changes:
The name of the business process in the process designer will change, for example,
- Name in new process designer: business-process-name.bpmn - Business Processes
- Name in legacy process designer: business-process-name.bpmn2 - Business Processes (legacy)
- The extension of the business process will change from *.bpmn to *.bpmn2.
