Moving Data Without Breaking the Business That Depends On It
Data migration is rarely just “moving information.” It’s almost always more like surgery — the data is connected to processes, reports, integrations, and people who depend on it being right. Getting it wrong has real consequences: broken workflows, missing history, reports that no longer reconcile, and the trust issues that follow when nobody’s quite sure if the new system is correct.
SITEK approaches data migration carefully. We plan, validate, and verify— and we treat your data like the business asset it is.
Data Migration
Whether you’re moving from a legacy system to a modern one, consolidating multiple databases into one, or migrating from on-premises infrastructure to the cloud, our team handles data migrations end-to-end. That includes the parts people often underestimate: cleaning up data that’s accumulated quirks over years, mapping fields that don’t line up cleanly between systems, and validating that the migrated data correctly matches the source.
We work with you to define what “successful migration” should look like — not just “the data made it across” but “the data made it across correctly, completely, and in a form the new system can properly use.”
ETL Development
ETL — extract, transform, load — is the broader category of moving and reshaping data between systems. It’s what makes data warehouses, reporting systems, and analytics platforms possible. Our ETL development work covers the full process: pulling data from source systems, transforming it into a useful shape, and loading it into wherever it needs to live.
We build ETL processes that are reliable, observable, and maintainable. That last part matters more than people realize. A lot of ETL ends up as fragile glue code that nobody wants to touch — and that’s a problem when the source systems change or new requirements come in. We build ETL processes that can easily be maintained over time.
Data Warehousing
A data warehouse is the place where data from across your business comes together in a form that can be analyzed and reported. Building a good data warehouse takes more than just dumping data from your transactional systems into a separate database. It requires thoughtful design — facts and dimensions, naming conventions, slowly changing dimensions, the kinds of decisions that make the difference between a data warehouse that gets used and one that doesn’t.
Our team has built and maintained data warehouses for businesses that need real visibility into their operations. We focus on warehouses that are built for today’s needs and tomorrow’s questions.
Common Data Projects
- Migrating from legacy systems (including older Microsoft Access databases) to modern platforms
- Building data warehouses to support business intelligence and reporting
- Developing ETL pipelines that move data between operational systems and analytical ones
- Cleaning up and consolidating data that has accumulated across multiple systems over time
- Migrating on-premises databases to Azure or AWS
