After migration, the extensibility functionality is hosted in the Cloud Assembly service and managed by the Event Broker.

Depending on your source environment, you might need to modify existing workflows and action code to optimize extensibility in vRealize Automation 8. Modifications and new functionality include:
  • vRealize Orchestrator plugin support
  • Postgres and Microsoft SQL server database access
  • Rewriting workflow or action code for use with Cloud Assembly
  • Using subscriptions with Cloud Assembly

For more information on extensibility changes between vRealize Automation 7.x and 8.x, refer to the vRealize Automation 8.x Extensibility Migration Guide.
