We specialize in APO to IBP migrations, helping organizations transition smoothly to the cloud-based planning platform. With APO mainstream maintenance ending in 2027, we recommend starting your migration planning in 2026 to ensure adequate time for a well-executed transformation. We can help you evaluate the next steps through an initial assessment of your planning processes in SAP APO and the definition of a potential roadmap towards SAP IBP.
If you’re currently on APO, 2026 is the critical year to begin your migration planning. Complex migrations typically require 12-18 months, and starting in 2026 allows you to complete migration before APO mainstream maintenance ends in 2027. Early planning also secures budget, resources, and allows for a strategic transformation rather than a rushed technical upgrade.
