πŸ”΅ Special Migrations (Camunda 8.9)
πŸ“Œ Event Subprocess β†’ Preserved with Review
Node: Timer-Driven Event Subprocess (SubProcess_Event)
Original: Event Subprocesses are supported in Camunda 8.9 but require careful review during design
Converted: Preserved as Event Subprocess (requires design review)
Reason: Event subprocesses with interrupting start events should be reviewed during offline BPMN redesign to ensure correct behavior in Camunda 8.9.
Recommendation: Review event subprocess logic and ensure service tasks are idempotent in the redesigned BPMN
Camunda 8 Way: Use Event Subprocesses with proper configuration. Consider using call activities for complex logic.
Status: Completed - Design Review Recommended
βœ… Improvement Suggestions
[HIGH] Process has 31 nodes - Consider splitting into smaller subprocesses
πŸ’‘ Break down into logical subprocesses or call activities for better maintainability
πŸ—οΈ Camunda 8 Way: Use SubProcess with call activities for reusable logic
[MEDIUM] 10 User Task(s) have no forms defined
