Now that we’ve covered what the end of support for SAP Commerce on-premise means and the options available after 31 July 2026, the next logical question is: How much will the migration cost?
It’s one of the first questions management asks when planning a budget. At the same time, it’s one of the hardest to answer because there is no one-size-fits-all price.
An even more important question might be: What does a migration actually include? Because the cost of a migration isn’t simply the cost of moving your application to the cloud. In most cases, it’s an opportunity to modernise your entire e-commerce platform.
Why Do SAP Commerce Migration Costs Vary So Much?
Just like building a house, the final cost depends on the scope of the project.
A B2B portal with a handful of integrations is a very different project from a global e-commerce platform connected to dozens of business systems.
Another major factor is the type of migration your business actually needs.
Some organisations simply want to move to a supported cloud version. Others see the migration as an opportunity to reduce technical debt, modernise their architecture or simplify business processes.
That’s why no two migration projects are the same.
Migration Is More Than Moving an Application
When people talk about migrating SAP Commerce on-premise, they’re often thinking about moving an application from one environment to another.
In reality, most migration projects also involve:
- modernising the application architecture,
- reducing technical debt,
- reviewing existing customisations,
- updating or replacing integrations,
- refreshing the storefront,
- migrating business data,
- testing and post-go-live stabilisation.
One of the biggest mistakes is trying to migrate everything exactly as it is today.
Many features that required custom development years ago are now available as standard capabilities in modern commerce platforms. Migration is therefore the perfect opportunity to ask yourself:
Does everything we’ve built over the years still create value for the business?
Removing unused functionality or simplifying business processes can significantly reduce not only the migration cost, but also future maintenance costs.
What Has the Biggest Impact on Migration Costs?
1. Customisations
The biggest cost driver is usually not SAP Commerce itself, but the amount of custom functionality that has been built over the years.
If your platform includes custom workflows, pricing logic, approval processes or complex B2B functionality, the migration will naturally require more effort.
However, not everything necessarily needs to be migrated. A technical assessment often reveals functionality that’s now available out of the box—or no longer used by the business at all.
2. Integrations
Modern e-commerce platforms rarely operate in isolation.
Typical integrations include:
- SAP ERP or SAP S/4HANA,
- PIM,
- CRM,
- payment gateways,
- warehouse and logistics systems,
- marketing automation platforms.
Each integration needs to be reviewed, tested and, in many cases, adapted to the new environment. In enterprise projects, integrations are often one of the largest contributors to the overall budget.
3. Storefront and User Experience
Some organisations want to keep their existing storefront.
Others use the migration as an opportunity to redesign the customer experience or adopt a more modern frontend architecture.
This decision can significantly affect both the project scope and the budget.
4. Data Migration
Migration isn’t just about moving the application.
Products, customers, orders, pricing data and historical records all need to be transferred safely, ensuring the new platform can go live without disrupting day-to-day business operations.
What Are the Typical Costs?
Every project is different, but based on enterprise e-commerce projects, it’s possible to define some indicative budget ranges.
- Migration to SAP Commerce Cloud, while retaining most of the existing functionality, typically ranges from €80,000 to €180,000.
- Migration combined with platform modernisation, integration updates or a new storefront generally falls between €180,000 and €500,000.
- A complete replatforming project to a different commerce platform often starts at €300,000+, depending on the project’s complexity and scope.
These figures are intended as general guidance for enterprise projects. The actual budget will always depend on your specific environment, architecture and business requirements.
And What's the Cost of Staying On-Premise?
When evaluating their options, many organisations focus solely on the cost of migration.
Far less attention is paid to the cost of not migrating.
Those costs gradually accumulate through:
- increasing maintenance costs for legacy systems,
- growing investment in custom development,
- more complex integrations,
- higher security risks,
- slower delivery of new features.
These costs rarely arrive as a single invoice. Instead, they build up over time and steadily increase the total cost of operating your platform.
That’s why the real comparison shouldn’t be the cost of migration versus zero. It should be the cost of migration versus the long-term cost of continuing to run an unsupported platform.
Where Should You Start?
If you want a realistic budget estimate, don’t start by choosing a platform – or even a technology partner.
Start with a technical assessment.
A good assessment should answer questions such as:
- How extensive are the current customisations?
- Which integrations will require changes?
- How much technical debt has accumulated?
- Which custom features still provide business value?
- Which parts of the solution can be retained?
- Which components would be more cost-effective to replace?
Only with this information can you build a realistic project timeline and budget.
How We Can Help
At Cassovia Code, we help companies prepare for migration long before any final technology decisions are made.
Through a technical assessment, we evaluate your current SAP Commerce environment, identify technical and business risks, review your integrations and customisations, and provide recommendations together with an indicative budget estimate.
This gives you a clear understanding of what’s ahead—allowing you to make decisions based on facts rather than assumptions.
