pub fn upgrade(
_snapshot: Vec<StateUpdateKind>,
) -> Vec<MigrationAction<StateUpdateKind, StateUpdateKind>>Expand description
No-op migration. All types are JSON-compatible between v79 and v80. The only change is adding new audit log event types and fields.
There is one exception, AlterSetClusterV1, which was changed in an
incompatible way. We can do this only because we know this audit event has
never been written before.
