+Assuming a chain upgrades at block `n`, the procedure should run as follows:
 
 - the old binary will halt in `BeginBlock` at block `N`. In its store, the ConsensusVersions of the old binary's modules are stored.
 - the new binary will start at block `N`. The UpgradeHandler is set in the new binary, so will run at `BeginBlock` of the new binary. Inside `x/upgrade`'s `ApplyUpgrade`, the `MigrationMap` will be retrieved from the (old binary's) store, and passed into the `RunMigrations` functon, migrating all module stores in-place before the modules' own `BeginBlock`s.
