A practical UK guide to heterogeneous database migration tools.

Key insights: 🔹 Migration is application + governance, not just data copy 🔹 Four layers: data movement, schema/code conversion, app compatibility, ops/governance 🔹 Evaluate tools on CDC depth, schema conversion, validation, security, operational fit 🔹 Run a proof of feasibility with representative workloads 🔹 Address UK GDPR, encryption, audit trails, data residency

A must-read for UK IT leaders, CTOs, and database architects.
