So you could try to cheat. HSM Migrate/RECALL with an updated DATA Class.
DATACLAS is only valid when the dataset is created. So you cannot assign EA/EF without a DEL/DEF function (yes there are other elements that can be altered in the DATACLAS and be effective. EA/EF is not one of them). Or create a new ZFS, copy old ZFS to new ZFS.
