What a data warehouse migration costs, and what the total includes
With Novuz, a data warehouse migration typically costs $25,000 to $40,000 for an estate under 1,500 components and $80,000 to $200,000 for 5,000 to 10,000, at a fixed price set by a $3,000 assessment. Price follows object count and complexity, not hours or terabytes, and Novuz publishes its ranges.
The ranges
How much does a data warehouse migration cost with Novuz?
The published ranges, by estate size. The exact price for your estate is fixed by the $3,000 estate assessment, delivered in three business days and credited in full.
| Estate | Components | Data | Typical duration | Typical price |
|---|---|---|---|---|
| Small | under 1,500 | under 25 TB | 5 to 6 weeks | $25k to $40k |
| Medium | 1,500 to 5,000 | 25 to 100 TB | 8 to 12 weeks | $40k to $80k |
| Large | 5,000 to 10,000 | 100 to 400 TB | 12 to 20 weeks | $80k to $200k |
| X-Large | over 10,000 | over 400 TB | 20+ weeks | from $200k |
“Migration cost is set by how much logic you have, not how much data.”
Components are schemas, views, functions, procedures, scripts, ETL jobs and workflows. Duration covers environment setup, conversion, data migration and validation; your own functional testing runs alongside.
Total cost
What is the total cost of ownership, including parallel running and validation?
Five lines make up a migration’s real cost. Most budgets miss the last two.
- Conversion: the price above, fixed from the assessment.
- Your team’s time: decisions, reviews, functional testing and cutover.
- The new platform: consumption from the first cutover domain onward.
- The old platform, still running: license, support and infrastructure until each domain is cut over.
- Parallel running and validation: the months both systems run while someone proves the numbers match.
Reconciling each object before cutover shortens line 5 from months to the cutover window of each domain, and that usually moves line 4 as well.
The renewal
What is the ROI of migrating before the renewal?
Compare two numbers on the same date. One is the renewal: license and support for the next term. The other is the move: the fixed price plus your team’s time, minus the old platform’s cost avoided after cutover. The assessment gives the second number in three business days. If the move is cheaper over the renewal term, the renewal is the return.
Compared
How does that compare with an SI-led rewrite?
Novuz is about 40% cheaper than an SI-led rewrite of the same estate, at a fixed price set before work starts. An SI-led rewrite is usually priced by the hour against an estimate made before the code is read.

What does this page not publish?
Industry-wide migration cost averages, which mix estates and methods too different to compare. When delivered-estate ranges are assembled under the Methodology rules, they are added here by estate band.

What would our estate cost?
The estate assessment answers it on your code: every object counted and banded, the dead code listed, and a fixed price in three business days, for $3,000, credited in full.
FAQ
Frequently asked questions
How much does a data warehouse migration cost?
With Novuz, typically $25,000 to $40,000 for under 1,500 components, $40,000 to $80,000 for 1,500 to 5,000, $80,000 to $200,000 for 5,000 to 10,000, and from $200,000 above that. The exact price is fixed by a $3,000 estate assessment, delivered in three business days and credited in full.
What drives the cost of a data warehouse migration?
The amount of logic: how many procedures, scripts, ETL jobs and workflows there are, and how complex they are. Data volume matters less. Novuz prices by object count and complexity after reading the estate, not by hours or terabytes.
How long does a data warehouse migration take?
With Novuz, typically 5 to 6 weeks for under 1,500 components, 8 to 12 weeks for 1,500 to 5,000, 12 to 20 weeks for 5,000 to 10,000, and 20 weeks or more above that. On delivered estates of 1,000 to 1,600 objects, typically 4 to 8 weeks from kickoff to reconciled output.
