pub fn upgrade(
_snapshot: Vec<StateUpdateKind>,
) -> Vec<MigrationAction<StateUpdateKind, StateUpdateKind>>Expand description
No-op migration. All types are JSON-compatible between v85 and v86.
The only changes are adding the new ClusterSystemConfiguration and
ReplicaSystemConfiguration collections (and their StateUpdateKind
variants) that back scoped feature flags. No existing data is rewritten.
