SAP NetWeaver is the technical foundation on which the entire SAP application suite was built for two decades — ECC 6.0, Business Suite, PI/PO integration, SAP Portal, the ABAP runtime environment, Java AS, and the initial SAP HANA integration layer all depend on or derive from the SAP NetWeaver platform. SAP's current strategy positions Business Technology Platform (BTP) as the successor to NetWeaver's middleware and integration capabilities, and S/4HANA as the successor to NetWeaver-based ECC. The commercial implication: SAP's maintenance investment in standalone NetWeaver has contracted materially, and SAP account teams use NetWeaver end-of-support deadlines as leverage to accelerate BTP and S/4HANA migration conversations.
For organisations running SAP NetWeaver AS ABAP, NetWeaver AS Java, NetWeaver PI/PO (Process Integration/Orchestration), or NetWeaver Enterprise Portal independently of their ERP migration roadmap, third-party support delivers 50–65% annual saving over SAP's standard 22% NLV support fee — without requiring BTP migration, without SAP Integration Suite subscription costs, and without forcing a Portal replacement decision under SAP's End of Extended Support deadlines.

NW 7.31 (AS ABAP/Java): Mainstream maintenance ended December 2018. Extended maintenance ended December 2020. NW 7.4 (AS ABAP): Mainstream maintenance ended December 2020. Extended to December 2025. NW 7.5 (AS ABAP, PI, Portal 7.5): Mainstream maintenance ends December 2025. Extended to December 2027. NW 7.50/7.51 (latest): Mainstream maintenance active to December 2027. For NW 7.4 and below, TPS is the commercially rational alternative to SAP's Extended Maintenance surcharge. See our SAP TPS complete guide for the full maintenance timeline.
SAP BTP and Integration Suite — The Replacement Cost SAP Omits
SAP Business Technology Platform (BTP) is SAP's cloud platform layer that positions as the integration, extension, and analytics backbone for S/4HANA and cloud application landscapes. SAP account teams present BTP as the natural evolution from SAP NetWeaver PI/PO integration and NetWeaver Portal — technically accurate, commercially loaded. The BTP Integration Suite subscription for a mid-market enterprise (500 integration messages/hour, 10 integration flows) costs approximately £120K–£380K per year depending on message volume tier and bundling with BTP Extension Suite.
For organisations running SAP NetWeaver PI/PO for B2B integration (EDI, IDOC, RFC), internal system integration (HR to Payroll, SD to WMS), and regulatory interfaces (HMRC VAT/MTD, NHS Spine, PRA/FCA reporting), the migration from PI/PO to BTP Integration Suite requires re-implementing all existing integration flows — converting PI/PO message mappings (XSLT/Java, Graphical Mapping) to BTP IFlow configurations, re-certifying all partner connections, and rebuilding the monitoring and alert infrastructure. Our SAP PI/PO support guide covers the PI-to-BTP migration cost components in detail.

NetWeaver PI/PO to BTP Integration Suite — Why TPS Is the Better 2026 Decision
SAP PI/PO migration to BTP Integration Suite is a legitimate long-term architectural decision that many large enterprises are planning as part of their broader S/4HANA transformation. What it is not: a 6–12 month project that can be completed in parallel with ongoing business operations. A realistic timeline for migrating a PI/PO landscape with 50–200 active integration flows (typical for a mid-large SAP landscape) is 18–36 months, with SI project costs of £300K–£2M+ depending on the complexity of existing mappings and the number of B2B partner connections that require re-certification.
Third-party support on SAP NetWeaver PI/PO provides the operational stability and cost reduction necessary to plan and fund that migration properly — rather than executing it under pressure from SAP's Extended Maintenance expiry deadline with an SI partner that is measuring project duration in calendar months while billing daily rates. The BTP Integration Suite subscription cost (typically £120K–£380K/year for mid-market) is an additional recurring cost that should be evaluated against the PI/PO TPS saving over the planning period before committing to a migration timeline.
