RHDG 8.2 StoreMigrator migration causes PersistenceException MalformedProtobufException invalid protobuf tag

Issue

When using the StoreMigrator to migrate the cache store files from Data Grid 7.2 to v8.2.1, the following issue happens:

migrator.properties:

target.type=SINGLE_FILE_STORE
target.cache_name=assignedproductcache
target.location= <location>
source.type=SINGLE_FILE_STORE
source.cache_name=assignedproductcache
source.location=<location>

The error:
