In Smartstore 5, Fluent Migrator is used for database migrations (no longer Entity Framework Migrations).
You can see some commented out examples in the DevTools module.
The GoogleMerchantCenter module also uses a migration to store additional product data in a separate database table. Requirements, so that this succeeds, can be seen there. This includes especially the IDbContextConfigurationSource implementation.
