A method for migrating between first and second service enablers in an open service architecture includes registering a second service enabler within open service architecture framework. The properties of the registered second service enabler are compared with the properties of at least one of first service enablers which determines if the second service is backward compatible to the first service enabler. Information concerning whether the second service enabler is backward compatible with the first service enabler is then forwarded to an application using the first service. Additional information that can be sent to the application in the same message includes, e.g., the fact that the second service enabler outdates a first one, a migration strategy and references to interfaces on the second service enabler that the application can already start using.
