Abstract

Implementations for data migration in a maintenance procedure executed on a software system include actions of providing a first access schema, through which a first version of an application accesses data in a database system, establishing an API-schema, through which at least one direct consumer accesses data in the database system, the API-schema including one or more proxy objects that are mapped to respective one or more objects of the first access schema based on metadata of the API-schema, the metadata providing a mapping and one or more object definitions, and in response to execution of a maintenance procedure: providing a second access schema, through which a second version of the application accesses data in the database system, switching to the second access schema, and revising the mapping of the API-schema, such that at least one proxy object of the API-schema maps to a respective object of the second access schema.
