Data Warehouse Migration in West Bengal
Dual running is not optional. Both systems run until the numbers agree, and only then does anyone move.
West Bengal runs on engineering and steel, jute and textiles, leather, tea and financial services, an older industrial base with substantial legacy-system modernisation work ahead of it. Where data warehouse migration earns its budget here usually follows directly from that mix.
Integration comes before intelligence. A model that cannot reach your systems of record is a demo with good manners. Six weeks to something running in production, not six quarters to a strategy document.

Questions
Do you cover all of West Bengal?
Yes, all 23 districts and 1,147 PIN codes. Delivery is remote-first, so coverage is genuinely statewide rather than limited to the cities we happen to have offices in.
Which West Bengal sectors do you work with most?
Across West Bengal the economy leans towards engineering and steel, jute and textiles, leather, tea, financial services. An older industrial base with substantial legacy-system modernisation work ahead of it.
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.
