I'm not sure not sure what you mean, so it's hard to answer.

In terms of migrations, EventSourced apps use migrations for the database backed projections, in the same way regular apps do. If the schema changes shape, you create a migration. So as your systems evolves, you'll get more and more migrations, like any standard web app.

Hope that helps, if it's not on the right track, let me know and I'll do my best to answer.
