How Ashok Leyland Migrated 230+ SAP PI Interfaces to SAP Integration Suite

Ashok Leyland is one of the world's largest commercial vehicle manufacturers and a flagship of the Hinduja Group. Like most SAP-led enterprises, its integration backbone had been built on SAP Process Integration (PI) over many years, carrying critical flows between SAP ERP, supplier systems, dealer networks and shop-floor applications.

Why the migration could not wait: SAP PI/PO end of support in 2027

SAP has set 2027 as the end of mainstream maintenance for SAP Process Integration and Process Orchestration. With 230+ active SAP PI interfaces supporting SAP ERP, supplier systems, dealer networks and shop-floor applications, the migration needed to protect business continuity while reducing manual rebuild effort. Tarento delivered the programme using its iVolve Automation Framework, moving critical interfaces to SAP Integration Suite on SAP Business Technology Platform with 60–80% automation across discovery, conversion and validation. The result was a cloud-first integration foundation ready for future SAP, supplier-network and IoT initiatives.

Migration objective: 230+ interfaces, no disruption, maximum automation

The target was clear. Move every active SAP PI interface to SAP Integration Suite on Business Technology Platform, keep production stable through the transition, and automate as much of the rebuild as the technology allowed. A like-for-like manual rewrite would have stretched the timeline and overloaded the integration team.

The Tarento approach: iVolve Migration Automation Framework

Tarento delivered the programme using iVolve, its proprietary migration automation framework for SAP integration estates. iVolve covers the parts of a PI to SAP IS migration that consume the most time when done by hand:

• Automated interface discovery across the existing PI landscape
• Conversion of source artefacts into SAP IS iFlows
• Smart mapping between PI message structures and SAP IS equivalents
• Built-in validation, testing and governance across the lifecycle

By pushing repetitive work into the framework, the team kept human attention on the interfaces that genuinely needed redesign rather than translation.

Why SAP Integration Suite was the right target

SAP IS sits on SAP Business Technology Platform and gives Ashok Leyland a single environment for integration, extension, data services and event mesh. Native adapters for SAP ERP and S/4HANA cut connector overhead, and the platform aligns with SAP's published roadmap well past 2027. That alignment matters. Future S/4HANA, analytics and supplier-portal work will plug into the same foundation without another platform shift.

Results: 230+ interfaces migrated with 60–80% automation The programme delivered against every objective set at kick-off:

• 230+ SAP PI interfaces successfully migrated to SAP Integration Suite
• 60–80% automation achieved across discovery, conversion and validation
• Significant reduction in manual build effort, project timeline and overall cost
• Business continuity preserved throughout the migration

Automation absorbed the repetitive elements of the migration, which kept the team's attention on the interfaces that needed genuine design judgement.

A scalable integration foundation for what comes next

Ashok Leyland now runs on an integration layer that scales with cloud workloads, supports event-driven extensions and matches the rest of its SAP investment. The PI/PO deadline is no longer a risk on the roadmap, and the platform is ready for the next wave of S/4HANA, supplier-network and IoT projects without another migration in between.
