Upgrading the SDL Tridion 2013 SP1 HR1 Context Engine Cartridge
As of SDL Web 8, the Context Engine exists in two forms: as a Context Engine Cartridge for the Ambient Data Framework, like before; and as a Context Engine Service client and a Context Engine Service. To upgrade the Context Engine Cartridge, upgrade the resources for the Cartridge itself; to migrate to the alternative Context Engine setup, install that setup.
