SAP PO to SAP Integration Suite migration is the process of moving existing integration flows, message mappings, and connections from on-premises SAP Process Orchestration to SAP’s cloud-native integration platform. Companies migrate to reduce infrastructure costs, gain access to prebuilt connectors, and prepare their integration landscape for S/4HANA and SAP BTP. This guide walks through the assessment tools, migration steps, and common challenges involved, using the same tooling SAP itself recommends for the transition.
What is SAP Integration Suite?
SAP Integration Suite (formerly SAP Cloud Platform Integration) is an integration platform that enables companies to quickly establish reliable communication between their existing on-premises systems and cloud services. It provides a unified platform to connect to any SAP or non-SAP application, helping companies reduce integration costs, increase data accuracy, and improve time to value.
The platform supports a wide range of integrations, including web services, databases, and file-based systems, and gives customers access to a large catalog of prebuilt integration packages to get up and running quickly. It also offers the flexibility to scale up or down and mix different integration services as your landscape evolves.
Before You Start: Run the SAP Migration Assessment
Before migrating a single integration flow, use the SAP Migration Assessment Tool, which is included with your SAP Integration Suite subscription. This tool scans your existing SAP PO landscape and reports which integration scenarios can be migrated automatically, which need redesign, and which are no longer needed. Running this assessment first prevents the most common migration mistake: discovering mid-project that a business-critical interface was never accounted for in the migration plan.
SAP PO to SAP Integration Suite Migration: Step by Step
Migration from SAP PO (Process Orchestration) to SAP Integration Suite (SAP CPI) is a critical process for businesses, and it requires planning before any technical work begins.
1. Assess the Existing SAP PO Environment
Identify existing integrations and processes that need to be migrated, using the Migration Assessment Tool’s output as your starting inventory. This step should include a review of the existing integration architecture, design, and development so nothing gets missed once the technical migration begins.
2. Connect SAP PO to SAP Integration Suite via Cloud Connector
Because SAP PO is an on-premises system, you need the SAP Cloud Connector to securely link it to SAP Integration Suite in the cloud. Cloud Connector acts as a secure tunnel between the cloud platform and your on-premises landscape without exposing your systems directly to the internet, which is what makes the rest of the migration possible.
3. Migrate Integration Flows and Message Mappings
With connectivity established, use the SAP Migration Tool to convert your integration flows, message mappings, and configurations from SAP PO into SAP Integration Suite’s iFlow format. Pay particular attention to dependent objects such as imported archives and function libraries used in your Message Mapping objects; these are the pieces most commonly missed in a manual migration.
4. Test and Validate Every Migrated Interface
Any integration or process you migrate needs to be tested and validated to confirm it works correctly in the new environment before you cut traffic over. Testing tools like Postman are commonly used here to verify that a migrated integration flow returns the same response as the original SAP PO interface.
5. Monitor Performance and Support End Users
Once all required integration flows and processes are migrated, monitor their performance in SAP Integration Suite and adjust as needed. It’s equally important to make sure end users are comfortable in the new environment and can use the new integration flows effectively, since a technically successful migration can still fail on adoption.
What are the Challenges When Migrating from SAP PO to SAP Integration Suite?
- Assessing the scope of the migration: You need to determine the scope of the migration and map the existing SAP PO architecture and processes to the new architecture before work starts.
- Integration with existing systems: All systems and applications connected to SAP PO need to be reconnected to SAP Integration Suite, which means reconfiguring integration details and connection points.
- Security and data protection: Security and data protection measures need review and updates to keep data safe during the migration, especially where Cloud Connector now bridges on-premises and cloud environments.
- Migration of existing data: All data stored in the SAP PO system must be migrated and understood correctly by the new system.
- Training your team: Employees need training on the new SAP Integration Suite environment for the migration to succeed operationally, not just technically.
How Does This Fit Into a Broader SAP BTP Strategy?
SAP PO to SAP Integration Suite migration is rarely an isolated project. Because SAP Integration Suite runs on SAP Business Technology Platform (SAP BTP), most organizations plan this migration alongside a broader move to S/4HANA or other BTP services, so integration, data, and application layers modernize together rather than in separate waves.
SAP PO to SAP Integration Suite Migration: FAQ
What tools does SAP provide for this migration?
SAP provides the Migration Assessment Tool to evaluate your existing PI/PO landscape and the Migration Tool to convert integration flows, mappings, and configurations into SAP Integration Suite’s format, both included with your Integration Suite subscription.
How long does a SAP PO to SAP Integration Suite migration take?
Timelines depend heavily on how many integration scenarios you have and how customized your existing mappings are. A landscape with a handful of standard interfaces can migrate in weeks, while a large, highly customized PO landscape can take several months.
Can I migrate in phases instead of all at once?
Yes. Most organizations migrate integration scenarios in phases, starting with lower-risk interfaces to validate the process before moving business-critical integrations, rather than attempting a single cutover.
Do I need SAP Cloud Connector if I’m already fully on S/4HANA Cloud?
If any part of your landscape, including SAP PO itself, remains on-premises during the migration, you need Cloud Connector to bridge it securely to SAP Integration Suite until that on-premises dependency is fully retired.
