From https://crates.parity.io/frame_support/attr.pallet.html#checking-upgrade-guidelines

storages now use PalletInfo for module_prefix instead of the one given to decl_storage: Thus any use of this pallet in construct_runtime! should be careful to update name in order not to break storage or to upgrade storage (moreover for instantiable pallet). If pallet is published, make sure to warn about this breaking change.

migrate order

Ordering migrations

If you are running on a Substrate version after commit #bd8c1cae, the storage migration order has been updated to:

1. Custom on_runtime_upgrade
2. frame_system::on_runtime_upgrade
3. All on_runtime_upgrade functions defined in all included pallets.

The reason is to cater for scenarios where one needs to write custom code to make
frame_system::on_runtime_upgrade run and return successfully.
Refer to the details here.
