🔵 Special Migrations (Camunda 8.9)
📌 Event Subprocess → 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
✅ Improvement Suggestions
[HIGH] Process has 31 nodes - Consider splitting into smaller subprocesses
💡 Break down into logical subprocesses or call activities for better maintainability
🏗️ Camunda 8 Way: Use SubProcess with call activities for reusable logic
[MEDIUM] 10 User Task(s) have no forms defined
💡 Create and attach Camunda 8 forms to these user tasks
🏗️ Camunda 8 Way: Use Camunda 8 Forms with zeebe:formDefinition

📌 Conditional Event JUEL → FEEL
Node: Temperature Alert (StartEvent_Conditional)
Original: Conditional Events are NEW in Camunda 8.9 (first-class support introduced)
Converted: Preserved as Conditional Event with JUEL expressions converted to FEEL

📌 Escalation Event → Escalation Event (with FEEL)
Node: Escalation (EscalationEvent_Timeout)
Original: Escalation Events ARE FULLY SUPPORTED in Camunda 8.9
Converted: Preserved as Escalation Event with JUEL expressions converted to FEEL
Reason: Camunda 8.9 supports Escalation Events natively as non-critical events. Execution continues at both throw and catch locations.
Recommendation: Review escalation event configurations and FEEL expressions in the redesigned BPMN
Camunda 8 Way: Use Escalation Events with FEEL expressions for non-critical communication
Status: Completed - Preserved with FEEL expressions
📌 Event Subprocess → Preserved with Review
Node: Error Event Subprocess (EventSubProcess_Error)
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.
