SYSTEM, DEVICE AND METHOD FOR ACHIEVING SERVICE UPGRADE

摘要

A system, an apparatus, and a method for upgrading a service are provided herein. The method includes: loading and registering the upgraded new service version, and retaining the service of the old version; receiving a service processing request, and sending the received service processing request to the service processing device which is loaded with the service version corresponding to the service processing request according to the stored mapping relation between the service processing request and the information about the version of the service. In this way, the data loss is reduced or avoided in the service upgrade process, and the service works normally after the upgrade.
