1. A computer-implemented method of processing a database conforming to a first schema, comprising: generating, using a hardware processor, a delta file based upon a comparison between the first schema and a second schema different than the first schema; updating, using the delta file, the database to conform to the second schema; translating data of the database in accordance with a metadata file; disabling, prior to the translating, a requirement of the first schema that applies to the data; and enabling, responsive to the translating being completed, a requirement of the second schema, wherein the updating the database does not change the data in the database.
