Legacy data

Legacy data covers OpenCRVS capabilities for bringing historical civil registration records into the eRegistry.

There are two related capabilities:

• Data migration — for historical records that already exist in a digital source, such as a previous CRVS database, spreadsheet, or another electronic register.

• Digitise paper records — for historical records that exist only in physical sources, such as register books, certificate counterfoils, bound volumes, or archive files.

Both capabilities aim to make historical civil registration records usable in OpenCRVS for search, certified copies, correction, reporting, audit and interoperability, subject to the same record lifecycle, access control and configuration principles as records created in OpenCRVS.

These Functional Architecture pages describe what OpenCRVS supports and the principles that apply. For project planning and readiness activities, see Migrate legacy data. For technical implementation guidance, see Legacy Data migration.
