A system can include an upgrade system manager. The upgrade system manager can be configured to communicate with an upgrade database that employs a given schema. The system can also include a legacy system manager configured to communicate with a legacy database that employs a different schema, wherein the legacy database contains a subset of the data stored at the upgrade database. The legacy database can be configured to provide a forward migration trigger to the upgrade system manager in response to detecting an update to the legacy database. The upgrade system manager can further be configured to determine whether data received from an application configured to produce data for the upgrade database is to be provided to the legacy database.
