Finance System's Legacy ABS Migration Framework supports institutions moving off an existing core banking system without a disruptive single cutover. The framework covers connector-based synchronization, reconciliation, historical-data access, and a staged, account-by-account or product-by-product transition to Finance System's own ledger.

• Read/sync integration with the External ABS during the transition period
• Reconciliation tooling to validate balances before cutover
• Historical-access support so nothing is lost mid-migration
• Institution-controlled pace — nothing forces a big-bang cutover

External ABS integration is described here as a migration/connector capability, not as the platform's own core — Finance System's own ledger is the target of the migration, not a dashboard layered on the legacy system.
