Upgrading an original repository of data is disclosed. A repository is defined by a set of schema structures and data contained therein. A copy of the original repository is exported. The set of schema structures of the original repository is modified to create a set of schema structures of the upgraded repository. Schema structures that are not present after the upgrade are deleted after data migration is completed. Data is migrated to the set of schema structures of the upgraded repository. Data includes existing data from the original repository and seed data for the upgraded repository. Existing data is copied into the appropriate schema structures of the upgraded repository. Seed data is inserted into new schema structures of the upgraded repository. The set of schema structures of the upgraded repository are validated against a standard set of schema structures corresponding to a properly upgraded standard repository to detect any errors.
