There is disclosed a system for migrating records in a database from a source database schema to a target database schema. A request is received to delete a state from the source schema. The state is marked as the redundant state. A resultant state is identified to which to migrate database records in the redundant state and a valid migration path is calculated between the redundant state and the resultant state.
