withSerializerUpgradesAllowed

@Nonnull
public RegisteredKeyAndUserKeyValueStateBackendMetaInfo<N,UK,S> withSerializerUpgradesAllowed()

Description copied from class: RegisteredStateMetaInfoBase

create a new metadata object with Lazy serializer provider using existing one as a snapshot. Sometimes metadata was just created or updated, but its StateSerializerProvider will not allow further updates. So this method could replace it with a new one that contains a fresh LazilyRegisteredStateSerializerProvider.

Overrides:
