# Week13 On my *[merged PR](https://github.com/sigp/lighthouse/pull/7917)*, I'm still waiting on Michael to do his magic. This week, I focused on adding **[schema migration support for Slasher when using the Redb backend](https://github.com/sigp/lighthouse/pull/8084).** Until now, Redb in Slasher didn't support automatic schema upgraded the way the Beacon Node does. This work brings the two line, ensuring that operators running Slasher on Redb can seamlessly upgrade without manual intervention. ## Work completed: - Implemented schema migration support for Slasher with Redb backend. - Added `upgrade()` handling in `redb_impl.rs` and wired it through `interface.rs` and `migrate.rs`. - Fixed clippy issues: - Boxed large enum variants (`RwTransaction`) - Collapsed nested if-let blocks. - Ran Lighthouse beacon node + Slasher on Holesky with Redb backend, upgrade succeeded. ## In progress / Next steps: - Ran Lighthouse beacon node using Redb + Slasher on Holesky with Redb backend, to test upgrade, but test is not acknowledging my code/branch yet. Still trying to figure that out. - Opened PR for review (`slasher-redb-upgrade`) — waiting on feedback. - Need to confirm with maintainers if boxing in `RwTransaction` is the preferred long-term solution.
