Trait pallet_support::migration::StorageMigration

pub trait StorageMigration: OnRuntimeUpgrade {
    // Provided method
    fn migrate() -> Weight { ... }
}

To run both pre- and post-checks around every migration, we entangle methods of OnRuntimeUpgrade into the desired flow and expose it with migrate method.

This way, try-runtime no longer triggers checks. We do it by hand.

Provided Methods

fn migrate() -> Weight
