Database Migration Services
Build repeatable database migration workflows that can be tested before the final cutover.
Database migration services from ETL Tools help move data between SQL Server, Oracle, PostgreSQL, MySQL, SQLite, Access, FoxPro, DBF and ODBC databases. The sensible approach is rehearsal, not heroics. Final migration day is a poor time to discover a date column has been living a double life.
Database migration usually combines mapping, cleansing and validation
We can build migration workflows that read from the old system, apply mapping and transformation rules, validate the result and write the target. The same workflow can run repeatedly on test extracts before the final migration.
- Schema mapping
- Type conversion
- Data cleansing
- Validation
- Referential integrity
- Reconciliation
- Migration testing
- Repeatable migration runs
- Cutover preparation
Common database migration sources and targets are supported
SQL Server, Oracle, PostgreSQL and MySQL
Map schemas, convert types, test constraints and reconcile source-to-target counts.
SQLite, Access, FoxPro and DBF
Extract older data, correct formats and prepare it for modern systems.
ODBC databases
Use ODBC where a direct connector is not available or an older system provides only driver-level access.
Migration testing reduces cutover risk
A migration workflow can be run on samples, partial extracts and full test loads. Counts, totals, duplicate checks and rejected rows can be reviewed before anyone touches the live system. This is less dramatic than a big-bang migration, which is exactly the point.
Send enough detail for a useful first answer
For a quote, include sample data if possible and describe the current source, required output and how often the process runs. A tiny example file is often more useful than a long meeting. Nobody has ever said that about a long meeting.
- Sample data or representative field list
- Source format and destination format
- Approximate record volume
- Transformation, validation and mapping requirements
- Processing frequency and delivery deadline
- Required output files, tables, reports or exception logs
Frequently Asked Questions
Can you migrate Access or DBF data?
Yes. Older Access, FoxPro and DBF data can be extracted, mapped, validated and loaded into a replacement system.
Can migration runs be repeated?
Yes. Repeatable test runs are strongly recommended before final migration.
Do you check referential integrity?
Yes. Parent-child relationships, missing keys and lookup references can be validated before loading.
Can you reconcile source and target data?
Yes. Reconciliation can include record counts, totals, missing records, duplicate checks and exception reports.
