Migrating Petals ESB runtime

No migration is required. Just reinstall your Petals topology with the Petals ESB 5.4.x runtime.

Migrating your services

At a runtime level, a large majority of service units running on Petals 5.3.x are compatible with Petals 5.4.x and do not require changes with the exception of:

• Petals SE Camel service units,
• Petals SE POJO service units.

At a development level, all service units need changes at unit test level because:

• API Jakarta EE 9 is now used by Petals ESB instead of API Java EE,
• and, all Petals component JUnit framework are based on JUnit 5 now:
  • 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 5.9.x.
