Legacy Database & Schema Migration Blueprint
End-to-end architectural planning for transitioning high-throughput relational and document stores with zero data loss and minimal operational disruption.
Target Engineering Audience & Result
Who This Engagement Is For
Engineering directors, lead database architects, and technical founders operating monolithic databases or legacy schema models under high concurrency.
Delivered Result & Outcome
A comprehensive, phase-by-phase technical roadmap specifying data mapping schemas, partition strategies, roll-forward dual-write pipelines, and automated cutover criteria.
Engagement Lifecycle
We analyze existing database traffic, schema constraints, queries, stored procedures, and table locking characteristics across your active services.
We formulate target schema structures, partitioning policies, and normalization or denormalization tradeoffs tailored to target storage engines.
We engineer the change data capture (CDC) pipeline or dual-write harness to continuously backfill historical partitions alongside live ingest.
We execute dry-run migration scripts on sanitized staging data to measure precise transfer throughput, lag tolerances, and verify checksum match rates.
Service Logistics
4 to 6 weeks engagement
Hybrid architecture review with on-site discovery workshops in Taiwan or remote pairing sessions
Fixed milestone engagement starting at NT$ 320,000 / $10,500 USD
