Migration waves
Accounts and products move in planned waves, each with a rehearsed cutover, reconciliation and a fallback agreed with operations.
Industry focus
Core banking modernisation
We move accounts, products and ledgers to a new core in planned waves, while the bank keeps trading.
Core banking modernisation means moving accounts, products and ledgers off an ageing core without stopping the bank. We plan the migration product by product, keep the old and new cores reconciled during parallel running and route payments through a hub, so channels are not rewired twice.
In the UAE, the outsourcing and technology risk rules of the Central Bank of the UAE shape how a new core is hosted and tested; in Saudi Arabia, SAMA's cyber security framework and outsourcing rules play the same role.
What the work involves
Parallel running
Old and new cores run side by side, with daily balance and transaction reconciliation until finance signs off.
Supervisory evidence
Test results, cutover logs and control changes kept in a form internal audit and the central bank can review.
Signs you are ready to start
Risk committees and internal audit ask for evidence at every stage, so these points are best settled before work starts.
- A target product map shows which products move in which wave.
- Finance has agreed how balances are reconciled during parallel running.
- The current core vendor's support and exit dates are known.
