// At the moment, the `parachains_configuration` crate has already had one runtime
// storage migration (performed as part of [#3575]). As the result a call to
// `StorageVersion::get::<Configuration>` will return `Some(1)`
//
// However, Polkadot is just about to have its first version of parachains runtime
// pallets and thus there is no existing storage which needs to be migrated. Above
// we just have set the active configuration of the actual version, i.e. the same as the
// version 1 on Kusama.
//
// The caveat here is when we deploy a module for the first time, it's runtime version
// will be empty and thus it will be considered as version 0. Since we want to avoid
// the situation where the same storage structure has version 0 on Polkadot and
// version 1 on Kusama we need to set the storage version explicitly.
