Module migration

A module that is responsible for migration of storage.

Modules

v0

This module contains data structures that are valid for the initial state of 0. (used with v1 migration).

v1

This migration updates RelayerRewards where RewardsAccountParams was used as the key with lane_id as the first attribute, which affects into_sub_account_truncating. We are migrating this key to use the new RewardsAccountParams where lane_id is the last attribute.

v2

The pallet in version 1 only supported rewards collected under the key of RewardsAccountParams. This migration essentially converts existing RewardsAccountParams keys to the generic type T::Reward.

Constants

STORAGE_VERSION

The in-code storage version.
