What changes when it is banking

Orqent Labs migrates warehouses in stages, reconciled at every step, so trust in the numbers survives the move.

In banking, core banking systems are not to be touched, so everything integrates around them. That single fact reshapes how data warehouse migration has to be built here, the guardrails, the approval points and the evidence trail are design inputs rather than things bolted on before go-live.

The workload we are most often asked to take on first is account opening documentation, usually integrated against loan management systems. Integration comes before intelligence. A model that cannot reach your systems of record is a demo with good manners.

Deployed across regulated and unregulated sectors, with audit trails where the regulator expects them. You own the code, the models where they are open-weight, and the documentation to run it without us.

Questions from this sector

Will this touch our core banking system?

No. We integrate through supported interfaces and read replicas, never by modifying the core.

How do you handle AML false positives?

Context enrichment and tuned scoring so alert volume matches investigator capacity, with every decision explainable in a case file.

How do you avoid breaking reports?

Row-level and aggregate reconciliation between old and new, plus dual running until the numbers agree. Consumers move in stages, never all at once.

Which warehouse should we move to?

It depends on workload and existing cloud. We model cost against your real query patterns rather than list pricing, and sometimes the answer is to stay.

How long does it take?

Driven by the number of downstream consumers far more than data volume. The inventory in week one gives a realistic estimate.

Data Warehouse Migration for banking, worth a conversation?

Tell us the workload and the regulation it sits under. We will tell you what is realistic.
