This is where most teams stumble \u2014 they don&#8217;t have a complete inventory of their ECC footprint. Here&#8217;s what you need to document:<\/p>\n<ul>\n<li><strong>System inventory<\/strong> \u2014 Every ECC instance you run (production, QA, dev, sandbox), with version and enhancement pack levels<\/li>\n<li><strong>Custom code analysis<\/strong> \u2014 Use SAP&#8217;s Custom Code Migration Analyzer to quantify Z-programs, user exits, BADI implementations, and modifications to SAP standard objects<\/li>\n<li><strong>Integration map<\/strong> \u2014 Every RFC, BAPI, IDoc, PI\/PO, and third-party connection. This is the #1 hidden complexity in most landscapes<\/li>\n<li><strong>Add-on assessment<\/strong> \u2014 Industry-specific and third-party add-ons. Are they compatible with S\/4HANA?<\/li>\n<li><strong>Data volume<\/strong> \u2014 How much historical data lives in your ECC system? Archive what you can before migration \u2014 less data means faster conversion and lower HANA memory costs<\/li>\n<li><strong>User and license audit<\/strong> \u2014 Current named user types, license counts, and Digital Access exposure. Clean this up before migrating to avoid paying for unused licenses<\/li>\n<\/ul>\n<p><strong>Tool to use<\/strong>: SAP Readiness Check 2.0 \u2014 it analyzes your ECC system and provides a pre-configured migration roadmap with simplification item check results.

Here&#8217;s what to model:<\/p>\n<ul>\n<li><strong>Extended maintenance cost<\/strong> \u2014 2% surcharge for 2028-2029, 4% for 2030. On a $1M annual maintenance bill, that&#8217;s an extra $20K-$40K per year<\/li>\n<li><strong>Migration project cost<\/strong> \u2014 System integrator fees, internal resource time, training, testing, and cutover. Budget 15-25% contingency<\/li>\n<li><strong>S\/4HANA license conversion<\/strong> \u2014 Your old ECC user types map differently to S\/4HANA. Full Use Equivalents (FUEs) can increase your license costs if you don&#8217;t optimize before converting<\/li>\n<li><strong>Infrastructure<\/strong> \u2014 On-premise vs. hyperscaler vs. RISE-managed. Each has a different TCO over 5-10 years<\/li>\n<li><strong>Hidden costs of waiting<\/strong> \u2014 As 2027 approaches, demand for SAP migration consultants and hyperscaler capacity will surge.

Why start now on ECC? Because the biggest cost driver in any migration is custom code remediation.

This is the single best investment you can make in a predictable outcome. <a href=\"https:\/\/adilfahim.com\/myblog\/sap-parallel-landscape-upgrades-conversions\/\">Setting up a parallel landscape<\/a> for this is a proven approach.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%E2%9D%93_Frequently_Asked_Questions\"><\/span>\u2753 Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Can_I_keep_using_ECC_after_2027\"><\/span>Can I keep using ECC after 2027?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes. The software will keep running. But you won&#8217;t receive standard security patches, legal\/regulatory updates, or SAP support under normal terms. You&#8217;ll need extended maintenance (paid premium through 2030) or third-party support like Rimini Street or Spinnaker Support. Many organizations with stable systems are choosing this path to buy time for a well-planned migration.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_much_does_extended_maintenance_cost\"><\/span>How much does extended maintenance cost?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>SAP charges a 2% premium on your existing maintenance fee for 2028\u20132029, and 4% for 2030. For organizations with large ECC estates, this can add $100K\u2013$500K+ per year. Third-party support providers like Rimini Street typically charge 50% of SAP&#8217;s standard maintenance fee \u2014 a significant saving if your system is stable and you don&#8217;t need SAP&#8217;s roadmap features.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Whats_the_difference_between_brownfield_greenfield_and_bluefield_migration\"><\/span>What&#8217;s the difference between brownfield, greenfield, and bluefield migration?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Brownfield<\/strong> (system conversion) \u2014 convert your existing ECC system directly to S\/4HANA. Keeps historical data and configurations. Fastest path but carries technical debt. <strong>Greenfield<\/strong> (new implementation) \u2014 build S\/4HANA from scratch. Cleanest outcome but highest effort and organizational change. <strong>Bluefield\/Selective Data Transition<\/strong> \u2014 a hybrid approach that moves selected data and processes while redesigning others. Increasingly the preferred option for complex landscapes.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Should_I_move_to_RISE_with_SAP\"><\/span>Should I move to RISE with SAP?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>RISE is the right choice if you want SAP to manage infrastructure while you focus on Clean Core and innovation. It&#8217;s expensive compared to on-premise S\/4HANA on hyperscaler infrastructure (roughly 20\u201335% higher 10-year TCO per some analyses), but includes BTP, Signavio, and Business Network. Evaluate based on your team&#8217;s cloud operations maturity and the strategic value of SAP-managed operations.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_happens_if_I_miss_the_December_2027_deadline\"><\/span>What happens if I miss the December 2027 deadline?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>You move to extended maintenance (2028\u20132030). Your system keeps running. But you lose access to SAP&#8217;s standard innovation stream, pay premium support fees, and face increasing difficulty finding consultants who still work on ECC. By 2028, most SAP ecosystem resources will have moved to S\/4HANA projects. Missing the deadline isn&#8217;t catastrophic, but it starts a clock \u2014 and every month of delay adds cost and risk.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The SAP ECC end of support 2027 deadline is real, but it doesn&#8217;t have to be a crisis. The organizations that come out ahead are the ones that start now with a clear plan. Run your landscape assessment this month. Start custom code cleanup. Begin the partner conversations. The 7 steps above are your playbook \u2014 follow them and you&#8217;ll navigate this transition on your terms, not SAP&#8217;s.<\/p>\n<p>What&#8217;s your current migration timeline?
