The Operator currently iterates over cache names, in the order that they are returned by the Infinispan server, to migrate caches from the source to target cluster. Consequently, it's possible that an indexed cache which relies on one or more .proto files will fail to start if it is processed before the ___protobuf_metadata cache. For example, all caches with a name that starts with a number or an upper-case character will be processed before ___protobuf_metadata.

To prevent this issue, the Operator should always migrate the ___protobuf_metadata and ___script_cache data before user caches.
