Data warehouse migration

For IT and BI managers and CTOs at mid-size and large companies

We migrate and modernise data warehouses.

From Teradata, Vertica, Oracle (Exadata), Netezza or Informatica to open tools you control. In stages, with the numbers reconciled and a parallel run until you are confident.

What we do

Two kinds of work for companies with a lot of data.

How a project runs

A migration in five steps. You decide after the test, before the move itself starts.

  1. DiscoveryWe map what exists, how much data there is and what depends on what: tables, loads, dependencies, SQL, response-time requirements and licences.
  2. Five-year business caseWhat you pay today, what the new setup costs and what the move costs, including the risks.
  3. Proof of concept on your dataWe convert a sample of SQL and pipelines and benchmark against your real workload. You decide after the test.
  4. Migration in stagesOne area at a time: data, pipelines and access rights are moved, and results are reconciled against the old system.
  5. Parallel run and cutoverBoth systems run side by side until you switch, with a way back if something goes wrong.

What you get

  • A review of your data warehouse: tables, loads, dependencies, SQL, response-time requirements and licences.
  • A five-year cost estimate: what you pay today, what the new setup costs and what the move costs.
  • A test on real data and real queries before you decide.
  • A migration where we check that the numbers match, with a parallel run until you are confident.
  • Open tools you control, so you can change supplier when you want to.
  • A fixed price after a short call.

Frequently asked questions

Which data warehouses can you move from, and to what?
From Teradata, Vertica, Oracle (Exadata), Netezza or Informatica to open tools you control: dbt Core, Airflow and PostgreSQL, and where it fits ClickHouse, Apache Iceberg with Trino, Python and AWS. The move is done in stages, with a parallel run until you are confident.
Will leaving our old data warehouse be cheaper?
We don't promise it will be free. We make a five-year cost estimate and measure on your own data before talking about savings. You get a fixed price after a short call.
What does a migration cost?
You get a fixed price after a short call. It covers mapping, cost case, test and migration in stages. The first call is free.
Do we have to move everything at once?
No. The move is done in stages, one area at a time, and results are reconciled against the old system.
What happens if something goes wrong at cutover?
Both systems run side by side until you switch, with a way back if something goes wrong.
Do you only do migrations?
No. We also do general data warehousing: ETL and data pipelines, data models and reporting.
