-**Users using `depinject` / app v2 do not need any changes, this is abstracted for them.**
-```diff
-+ app.BaseApp.SetMigrationModuleManager(app.ModuleManager)

-BaseApp added `SetMigrationModuleManager` for apps to set their ModuleManager which implements `RunMigrationBeginBlock`. This is essential for BaseApp to run `BeginBlock` of upgrade module and inject `ConsensusParams` to context for `beginBlocker` during `beginBlock`.

Returns an `abci.ResponseInitChain` to the underlying consensus engine, which can contain validator updates.
 * `ExportGenesis(ctx context.Context, cdc codec.JSONCodec)`: Calls the [`ExportGenesis`](./08-genesis.md#exportgenesis) function of each module, in the order defined in `OrderExportGenesis`. The export constructs a genesis file from a previously existing state, and is mainly used when a hard-fork upgrade of the chain is required.

The function returns a boolean value indicating whether the migration was executed or not and an error if fails.
-* `BeginBlock(ctx context.Context) error`: At the beginning of each block, this function is called from [`BaseApp`](../core/00-baseapp.md#beginblock) and, in turn, calls the [`BeginBlock`](./05-beginblock-endblock.md) function of each non-upgrade modules implementing the `appmodule.HasBeginBlocker` interface, in the order defined in `OrderBeginBlockers`.

It creates a child [context](../core/02-context.md) with an event manager to aggregate [events](../core/08-events.md) emitted from all modules.
