Since JDG-7175 was merged, the Memcached and RESP cache's are enabled by default. Unfortunately this breaks rolling upgrades, as the implementation is incorrectly using the "target" cluster as the source of truth for cache names when initiating the sync phase of the upgrade, process resulting in the following exception:

Instead the Rolling Upgrade process should always use the cacheNames defined on the source cluster as these are the caches that need to be synchronised with the new cluster.
