The Remote Store does not support transcoding yet, and the data conversions are done implicitly by combining the 'hotRodWrapping', 'marshaller' and 'rawValues' configurations.

The rolling upgrade process forces the remote store to use 'hotRodWrapping', that prevents consuming a cache that stores "application/x-java-objects", since it assumes the data is already in "application/x-jboss-marshalling" format, causing lots of internal issues.
