Step-by-Step Guide: Migrating SAP CPI (Neo) to SAP BTP Cloud Foundry for iFlows and Packages

Migrating SAP Cloud Platform Integration (CPI) from the Neo environment to SAP Business Technology Platform (BTP) Cloud Foundry (CF) involves exporting iFlows (integration flows) and packages from Neo, importing them into CF, and validating everything. This process ensures minimal disruption and preserves functionality.

The migration follows 4 main phases: Preparation, Export, Import, and Validation. It's based on official SAP guidance and can typically take 1–4 weeks depending on complexity.

Prerequisites

  • Access Rights: Admin access to CPI Web UI in both Neo and CF environments; SAP BTP Cockpit for CF subaccounts/spaces.
  • Environment Setup: Provision SAP Cloud Integration (part of SAP Integration Suite) in CF; create a dedicated CF space.
  • Tools Needed:
    • SAP CPI Web UI (primary for export/import).
    • SAP BTP CLI (optional for automation).
    • Backup tools for Neo data.
  • Other: Document all dependencies (e.g., connections, certificates); ensure network compatibility (e.g., VPC in CF).

⚠️ Tip: Test in a non-production CF space first. Backup Neo data fully.

Phase 1: Preparation (1–2 days)

  1. Verify Compatibility:
    • Log in to SAP BTP Cockpit and confirm CPI is provisioned in CF.
    • Check iFlows/packages in Neo for dependencies (e.g., external APIs, SAP S/4HANA connections).
  2. Document Configurations:
    • List all iFlows, packages, security artifacts (certificates, keys), and runtime parameters.
    • Export a full snapshot of Neo configurations via CPI Web UI > "Design" > "Export All."
  3. Set Up CF Space:
    • In BTP Cockpit, create a CF subaccount/space.
    • Assign roles (e.g., Cloud Integration Administrator) to users.

Phase 2: Export from Neo Environment (1 day)

  1. Access Neo CPI Web UI:
    • Log in to your Neo tenant's CPI (e.g., via https://<tenant>-iflmap.hcisb.int.sap.eu).
  2. Prepare Content:
    • Ensure all iFlows are versioned (not in draft state).
    • Go to "Design" > "Integrations" to view iFlows and packages.
  3. Export iFlows:
    • Select an iFlow > "Actions" > "Export" > Download as .iflow file (includes mappings/scripts).
  4. Export Packages:
    • Select a package > "Actions" > "Export" > Download as .zip file (includes all iFlows/sub-packages).
  5. Export Security Artifacts:
    • Go to "Security Material" > Select certificates/keys > "Export."
    • Save trusts and user credentials separately.

Output: A folder with .iflow files, .zip packages, and security exports.

Phase 3: Import into Cloud Foundry Environment (2–3 days)

  1. Access CF CPI Web UI:
    • Log in to your CF tenant's CPI (e.g., via BTP Cockpit > Services > CPI).
  2. Import iFlows:
    • Go to "Design" > "Integrations" > "Import."
    • Upload .iflow files > Map references (e.g., update connection names if needed).
    • Deploy the iFlow (test in "Started" mode).
  3. Import Packages:
    • In "Design" > "Packages" > "Import."
    • Upload .zip files > Resolve any hierarchy conflicts.
    • The structure (sub-packages, iFlows) should import intact.
  4. Import Security Artifacts:
    • Go to "Security Material" > "Add" > Upload certificates/keys from Neo exports.
    • Bind them to iFlows (e.g., assign to adapters like HTTP/SOAP).
  5. Reconfigure Connections:
    • Update system connections (e.g., "Connectivity" > Edit endpoints, credentials).
    • Handle CF-specific settings like VPC routing or proxies.

Tip: Import in batches (e.g., 5–10 iFlows at a time) to avoid errors.

Phase 4: Validation and Go-Live (3–7 days)

  1. Test iFlows Individually:
    • Send test messages via CPI Monitor > "Message Processing" > "Test."
    • Verify logic, mappings, and error handling match Neo behavior.
  2. Validate Security and End-to-End:
    • Check certificate trusts in connected systems.
    • Run full end-to-end tests (e.g., from source system to target).
  3. Monitor and Debug:
    • Use CF CPI Monitor for logs, traces, and analytics.
    • Compare performance metrics (e.g., throughput) with Neo.
  4. Go-Live:
    • Switch production traffic (e.g., update API endpoints).
    • Monitor for 24–48 hours.
  5. Decommission Neo:
    • Once stable, archive/delete Neo content and release resources in BTP Cockpit.

Common Challenges & Tips

  • Differences in CF: CF uses multi-target apps; adapters may need tweaks (e.g., JMS in CF is different).
  • Tools for Automation: Use SAP's Postman collections or Figaf tool for bulk export/import.
  • Downtime: Plan for 1–2 hours per iFlow during cutover.
  • Resources: Official SAP Guide here. For videos, search "SAP CPI Neo to CF migration" on YouTube.

If you encounter errors (e.g., import failures), share specifics for troubleshooting. This process ensures a smooth transition—start small!
