title: "migrations: prevent accidentally using inner unversioned migration instead of `VersionedMigration`"
doc:
- audience: Runtime Dev
description: |
Currently, it is possible to accidentally use inner unversioned migration instead of `VersionedMigration`
since both implement `OnRuntimeUpgrade`. With this change, we make it clear that `Inner` is not intended
to be used directly. It is achieved by bounding `Inner` to new trait `UncheckedOnRuntimeUpgrade`, which
has the same interface as `OnRuntimeUpgrade`, but can not be used directly for runtime upgrade migrations.
This change will break all existing migrations passed to `VersionedMigration`. Developers should simply change
those migrations to implement `UncheckedOnRuntimeUpgrade` instead of `OnRuntimeUpgrade`.
Example:
```
--- a/path/to/migration.rs
+++ b/path/to/migration.rs
@@ -1,7 +1,7 @@
-impl<T: Config> OnRuntimeUpgrade for MigrateVNToVM<T> {
+impl<T: Config> UncheckedOnRuntimeUpgrade for MigrateVNToVM<T> {
fn on_runtime_upgrade() -> Weight {
// Migration logic here
// Adjust the migration logic if necessary to align with the expectations
// of new `UncheckedOnRuntimeUpgrade` trait.

}
}
