Migrating to SAP HANA can transform your business—but what’s the real SAP HANA migration cost? It’s not just about software. Hidden fees, labor, and downtime add up fast. Let’s break down every expense so you’re never blindsided.
Understanding SAP HANA Migration: What It Really Means
Before diving into the SAP HANA migration cost, it’s essential to understand what migration actually entails. SAP HANA is an in-memory data platform that powers real-time analytics and high-performance applications. Migrating to it isn’t just a tech upgrade—it’s a strategic transformation that affects data architecture, business processes, and IT infrastructure.
What Is SAP HANA Migration?
SAP HANA migration refers to the process of moving your existing SAP ERP or other SAP systems from a traditional database (like Oracle, IBM DB2, or Microsoft SQL Server) to the SAP HANA in-memory database. This can be part of a broader digital transformation strategy or a step toward adopting S/4HANA, SAP’s next-generation ERP suite.
- Data is transferred from legacy systems into HANA’s high-speed in-memory environment.
- The migration may involve system conversion, landscape redesign, or full reimplementation.
- It enables real-time reporting, faster processing, and improved scalability.
Types of SAP HANA Migration
There are several paths to migrate to SAP HANA, each with different implications for cost and complexity:
System Conversion (Brownfield Approach): Upgrades your current SAP system to run on HANA without changing business processes.This is often less expensive but may carry technical debt.New Implementation (Greenfield Approach): Builds a fresh SAP S/4HANA system from scratch.Higher SAP HANA migration cost but offers a clean architecture and modern processes..
Selective Data Transition (Bluefield): A hybrid model where only selected data and processes are migrated.Offers balance between cost and innovation.”Migrating to SAP HANA isn’t just a database switch—it’s a business transformation that demands strategic planning and investment.” — SAP Expert, SAP.com
Key Factors Influencing SAP HANA Migration Cost
The total SAP HANA migration cost varies widely based on company size, system complexity, and migration strategy.Understanding the key cost drivers helps in budgeting accurately and avoiding surprises..
System Size and Complexity
The scale of your current SAP environment is one of the biggest cost determinants. Larger enterprises with multiple modules (FI, CO, MM, SD, PP, etc.), complex customizations, and extensive integrations will face higher migration costs.
- Small to mid-sized businesses might spend $200,000–$500,000.
- Large enterprises can expect costs from $1 million to over $10 million.
- Complex landscapes with multiple clients, legacy interfaces, and third-party integrations increase effort and risk.
Migration Strategy (Brownfield vs. Greenfield)
Your chosen migration path significantly impacts the SAP HANA migration cost:
- Brownfield: Typically 30–50% cheaper than greenfield. However, it may require extensive cleanup of legacy data and code, which can add hidden costs.
- Greenfield: More expensive due to reconfiguration and data migration, but results in a cleaner, more efficient system.
- Bluefield: Offers a middle ground, reducing cost while allowing selective modernization.
According to Gartner, organizations choosing greenfield report higher long-term ROI despite upfront costs.
Custom Code and Add-Ons
Many SAP systems rely on custom ABAP code or third-party add-ons. These must be analyzed, adapted, or replaced during migration.
- SAP offers tools like the Readiness Check and Code Inspector to assess custom code impact.
- On average, 20–40% of custom code may need modification or removal.
- Each hour of developer work adds $100–$200 to the SAP HANA migration cost.
Breakdown of SAP HANA Migration Cost Components
To fully grasp the SAP HANA migration cost, you need to dissect it into core components. Each plays a critical role in the total investment.
Licensing and Software Fees
Licensing is often the most visible—and sometimes the most misunderstood—part of the SAP HANA migration cost.
- SAP HANA database licenses are priced per processor core or user, depending on the model.
- For on-premise deployments, expect to pay $15,000–$25,000 per core annually.
- Cloud-based options (like SAP HANA Enterprise Cloud) offer subscription models, typically $100,000–$500,000+ per year based on usage.
- Additional costs may include SAP Solution Manager, Fiori licenses, and security tools.
It’s crucial to negotiate with SAP or your partner early. Licensing can consume 30–40% of the total SAP HANA migration cost.
Hardware and Infrastructure
If you’re deploying SAP HANA on-premise, hardware is a major expense. HANA requires high-performance servers with large RAM capacity (since it’s an in-memory database).
- Minimum RAM: 512 GB for small systems; large systems may need 2–4 TB or more.
- Server costs range from $50,000 to $500,000+, depending on size and redundancy needs.
- Vendors like HPE, Dell, Lenovo, and Cisco offer certified HANA appliances.
- Don’t forget networking, storage, and backup infrastructure.
Cloud migration reduces hardware costs but shifts spending to operational expenses (OPEX). Providers like AWS, Azure, and Google Cloud offer SAP-certified HANA instances.
Consulting and Implementation Services
Most companies rely on SAP partners or consulting firms to manage the migration. This is often the largest cost component.
- Hourly rates for SAP consultants range from $150 to $300+.
- Implementation timelines vary: 6–12 months for mid-sized firms, 18+ months for large enterprises.
- Key activities include system assessment, data migration, testing, training, and cutover.
- Top partners include Deloitte, Accenture, IBM, and Capgemini.
According to IDC, professional services can account for 40–60% of the total SAP HANA migration cost.
Hidden Costs in SAP HANA Migration
Beyond the obvious expenses, several hidden costs can inflate the SAP HANA migration cost if not anticipated.
Downtime and Business Disruption
During migration, systems may be offline or operate in a restricted mode. This can halt order processing, payroll, or supply chain operations.
- Even 24 hours of downtime can cost large companies $100,000+ in lost revenue.
- Phased migrations or parallel runs reduce risk but extend timelines and costs.
- Proper planning and communication are essential to minimize disruption.
Data Cleansing and Preparation
Migrating dirty or redundant data to HANA defeats the purpose of real-time analytics. Data cleansing is often underestimated.
- Legacy systems may contain outdated customer records, duplicate entries, or inconsistent master data.
- Data archiving tools (like SAP ILM) help reduce volume and improve performance.
- Expect to spend 10–20% of your project time on data quality initiatives.
Training and Change Management
New systems require new skills. Employees need training on HANA-based interfaces, reporting tools, and new business processes.
- Training costs include materials, instructor fees, and employee time.
- Change management ensures user adoption and reduces resistance.
- Companies that skip this often face low ROI and operational inefficiencies post-migration.
SAP HANA Migration Cost: On-Premise vs. Cloud
One of the biggest decisions affecting SAP HANA migration cost is deployment model: on-premise or cloud.
On-Premise Migration Costs
On-premise gives full control but requires significant upfront investment.
