The biggest moat in casino aggregation is not the technology. It's the assumption that switching will take six months and break the business. That assumption is wrong, and the aggregators who benefit from it know it.
Migration from one casino aggregator to another can be a 7-day operation. We've run it dozens of times for operators leaving incumbent contracts. This is the plan that works, the parts most teams overengineer, and the risks worth actually taking seriously.
Why migrations stall
Most aggregator migrations get stuck in the same places: nobody owns the cutover plan, the team tries to migrate everything at once, the legal review of the old contract takes longer than the technical work, and the engineering team rebuilds infrastructure that doesn't need rebuilding.
The 7-day plan
Day 1–2: Audit and export
Pull a full export from your current aggregator: active players, wagering history, open bonuses, pending settlements, KYC status, jurisdictional whitelisting. You're not migrating all of it — you need the shape to design the cutover.
- Player table — IDs, balances, currency, jurisdiction, KYC tier
- Open bonus state — pending free spins, deposit-match wagering progress
- Active sessions — players currently mid-game (handle these last)
- Provider whitelisting — which games are jurisdictionally available to which players
Day 3–4: Player ID map + wallet mirror
Generate the player ID mapping table — old aggregator player ID to Raise Engine player ID. Your wallet stays where it is; we just need to know which IDs map. Implement the two wallet callback endpoints (debit and credit) against your existing balance source of truth. Your wallet does not need to migrate.
Code Example
Day 5: Shadow run
Run Raise Engine in production alongside your incumbent. New player launches go to Raise Engine; existing live sessions stay on the incumbent until they end. No player notices anything. This is a 24-hour validation window — confirm wallet callbacks are firing correctly, settlements are matching the ledger, and reporting is consistent.
Day 6: Soft cutover
Flip the lobby's default game-launch route from the incumbent to Raise Engine. Active sessions on the incumbent finish naturally — incumbent stays warm for any session opened in the past 12 hours. New session launches all flow through Raise Engine. Open bonuses migrate via the bonus API — every pending free spin and wagering progress carries over.
Day 7: Decommission
Last active sessions on the incumbent close. Final ledger reconciliation against the incumbent's reporting. Issue the contract termination notice (this usually has 30–90 day notice periods in the contract — start the clock on day one if you can). Decommission the incumbent integration in your codebase.
What you do NOT migrate
The single biggest mistake in aggregator migration is migrating everything. You don't need to.
- Wallet — stays where it is. Raise Engine calls your wallet, same as the incumbent did.
- Player accounts — same. Identity and KYC live in your system. Aggregators just reference IDs.
- Historical wagering data — keep it where it lives. Your reporting layer queries both old and new for 12 months, then archives.
- Player communications — these stay in your CRM. Aggregator doesn't touch them.
Player communication
Most migrations are completely invisible to players. The launch URL changes, the game catalog might expand, the lobby looks the same. You generally do not need to send a migration notice unless required by your jurisdiction. If your players noticed the migration, something went wrong.
Risks worth taking seriously
A 7-day migration is not a low-risk migration — it's a focused one. The risks worth pre-empting:
- Bonus state mismatches — run an automated reconciliation between incumbent and Raise Engine bonus engines for 72 hours post-cutover
- Provider whitelisting gaps — confirm every jurisdiction has matching game availability before cutover, not after
- Settlement timing — incumbent contracts often delay final settlement 30–60 days. Plan for the cash flow gap
- Contract penalties — most aggregator contracts have early-termination clauses. Get legal involved on day one
Switching is cheaper than not switching
Every month you stay on a contract that doesn't fit is a month of compounding cost. The 7-day migration is real. We run it with operators every month. The hardest part is deciding to start.
