Database Migration
AI-powered migration from legacy and relational databases to modern cloud data platforms.
Database Migration
Migrate any relational or legacy database to modern cloud platforms with AI-powered schema recommendations, 4-dimensional data quality scoring, and zero-downtime execution via Change Data Capture.

How it works
1. Schema analysis and AI mapping
Claude AI analyzes your source schema and recommends a target schema, flagging:
- Type mismatches and implicit conversions
- Stored procedures that require manual review
- Missing indexes that would impact query performance
- Referential integrity gaps
2. Data quality scoring
Every table is scored across four dimensions before migration begins:
| Dimension | What it checks |
|---|---|
| Completeness | Null rates vs. expected population |
| Accuracy | Value distributions vs. known constraints |
| Consistency | Cross-table referential integrity |
| Uniqueness | Duplicate detection on key columns |
Tables scoring below your configured threshold are held for review.
3. Zero-downtime migration
Migration runs in two phases:
- Bulk load — historical data is loaded to the target in parallel batches
- CDC sync — Change Data Capture keeps source and target in sync until you're ready to cut over
4. Cut over
A final reconciliation check runs before cut over. If row counts, checksums, and quality scores all pass, the application is pointed at the new database. The process is reversible until the old database is decommissioned.
