Short answerReplacing Teradata, Oracle or SQL Server with Databricks swaps peak-sized capacity for elastic compute. Data copies easily; the real work is converting procedural logic such as BTEQ, PL/SQL and T-SQL, then reconciling results. Agree matching rules with business owners before conversion starts, so sign-off is fast.
Key takeaways
- Pay for compute when it runs.
- Procedural logic is the hard part.
- Agree matching rules with business owners up front.
Teradata, Oracle and SQL Server warehouses still power many enterprises. Their logic is often buried in stored procedures, BTEQ scripts and PL/SQL.
The economics
Traditional warehouses are sized for peak demand, so you pay for capacity even when it is idle. Elastic and serverless compute on Databricks scales with the work.
The hard part is logic, not data
Copying data is straightforward. Converting decades of procedural logic is not. We use LakeBridge and our accelerators for conversion, then review and test every critical path.
Reconciliation decides success
Users trust the new platform only when numbers match. We agree matching rules with business owners up front and report progress table by table.
Beyond like-for-like
Once migrated, the same data supports streaming, ML and agents. That is where the long-term value of the move comes from.
