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:

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

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 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.
