CALIGO migrates legacy data warehouses, on-premise platforms, and fragmented data estates to modern cloud architectures — with zero-downtime delivery, automated reconciliation at every stage, and a target architecture designed to last.
Legacy on-premise data warehouses — Oracle, Teradata, IBM — were built for a different era. They are expensive to maintain, difficult to scale, incapable of supporting modern analytical workloads, and increasingly misaligned with the regulatory requirements that demand real-time lineage, automated quality controls, and cloud-native data structures.
The cost of staying is rising faster than the cost of moving. Licence renewal costs compound annually. Maintenance engineering is increasingly scarce. And every new use case — real-time analytics, ML pipelines, regulatory layer automation — becomes harder to build on an architecture that was not designed for it.
CALIGO manages the full migration lifecycle — from target architecture design through cutover and post-migration stabilisation — with automated reconciliation and zero-downtime delivery.
Every migration is structured around three non-negotiable commitments — automated reconciliation throughout, zero downtime for critical systems, and a target architecture that is fit for the next 10 years, not just the next 2.
Every migration is underpinned by automated reconciliation — zero data loss is the standard, not the aspiration.
