Version 1.

In version 0 session historical pallet uses Session for storage module prefix. In version 1 it uses its name as configured in construct_runtime. This migration moves session historical pallet storages from old prefix to new prefix.


  • Migrate the entire storage of this pallet to a new prefix.
  • Some checks for after migration. This can be linked to frame_support::traits::OnRuntimeUpgrade::post_upgrade for further testing.
  • Some checks prior to migration. This can be linked to frame_support::traits::OnRuntimeUpgrade::pre_upgrade for further testing.
