5. The method as claimed in claim 1 , including: identifying a new service version based on monitored message traffic; and comparing the new service version with known service versions to match to an earlier version of the service.
1. A method for automatic transformation of messages between service versions, comprising: collecting message data of messages sent to two or more versions of a service; identifying message data as relating to a version of a service; inferring relationships between structure and content of messages sent to different versions of a service; creating message transformation rules based on the inferred relationships wherein creating message transformation rules creates transformation rules for transforming a message format for an earlier version of a service to a message format for a later version of the service; receiving a message for a version of the service using a proxy system; identifying if the message is for the earlier version of the service for which there is the later version of the service, using the proxy system; transforming the message using transformation rules for transforming the message format for the earlier version of the service to the message format for the later version of the service, using the proxy system; and forwarding the transformed message to the later version of the service, using the proxy system.
