Migrating Petals ESB runtime
No migration is required. Just reinstall your Petals topology with the Petals ESB 5.3.x runtime.
Migrating your services
At a runtime level, a large majority of service units running on Petals 5.2.x are compatible with Petals 5.3.x and do not require changes with the exception of:
At a development level, all service units having unit tests based on a Petals component JUnit framework and handling placeholder need changes:
- Petals SE Camel service units,
- Petals SE Flowable service units,
- Petals SE Mapping service units,
- Petals SE POJO service units.
We recommend to migrate all your service units even if no change is required at runtime level.
Migrating your custom CDK-based components
All your components based on Petals CDK must be upgraded to the Petals CDK 5.8.x.
