An export of customer names and balances is not a complete migration plan.
Inventory the records and live obligations
| Area | What needs a treatment decision |
|---|---|
| Accounts | Stable identity, duplicates, access and authentication changes |
| Verification and consent | Records that may transfer, require renewal or remain archived |
| Balances | Cash, bonus and other liabilities with the relevant currency |
| Restrictions | Limits, exclusions and unresolved account decisions |
| Active products | Open bets, unfinished rounds, tournaments and promotions |
| Operations | Complaints, disputes, payments and supplier cases still pending |
| History | Searchable records needed for support, reporting and authorized review |
Decide which items move to the new system and which remain in a controlled archive or are settled in the old one. Establish lawful data access and the cooperation required from current suppliers before promising a date.
Compare staged and single-cutover approaches
A staged move can reduce the amount changing at once, but it creates a period of shared responsibility and reconciliation across systems. A single cutover concentrates the change and may require a more demanding rehearsal and rollback plan.
Choose using the active obligations, operating capacity, downtime tolerance and supplier interfaces. A zero-downtime claim needs evidence for the actual design; it should not be assumed from the word “migration”.
Rehearse against a representative dataset
- Map fields and statuses.
- Perform the test move.
- Reconcile counts and financial totals.
Then inspect individual records, including restricted accounts, unusual currencies and active obligations. Totals alone can miss a balance assigned to the wrong account.
Test the player and staff journeys after transfer. Record discrepancies, their owners and the criteria for repeating the rehearsal. Preserve the mapping and accepted version used for production.
Define the cutover decision
Specify the freeze or synchronization process, final reconciliation, supplier activation and player communication. Name the person who authorizes go-live and the conditions that require a pause or rollback.
The rollback plan must account for transactions created after the new system starts. Restoring an older database without addressing new activity can create another reconciliation problem.
Send the source and destination systems, export rights, operating markets and live products. Include the obligations that cannot be interrupted so the migration can be scoped around them.
