How to migrate changes made to local db during developmnet to production?

The guide recommends adding some snippets to the database using the live_admin feature, here [1].

For the initial launch, the local database can simply be copied to the prod environment.

What would be the most sane way to deploy subsequent updates to the codebase and the database made in the development environment to production?

A guide on the recommended strategy would be of extreme help.

Read the linked create-a-blog guide, especially the live_admin section, and trace how the local database is copied for the initial launch. Compare that process with subsequent code and database updates between development and production. Done means documenting a clear, recommended deployment and data-migration strategy.
