The end of life for SAP ECC looms nearer every day. With support set to sunset in 2027 and the average migration taking up to 18 months for large enterprises, delaying the move to SAP S/4HANA becomes an ever-riskier proposition. Systems integrators may not have availability, or companies may struggle to find talent to guide them through the process. A recent survey found that only 12% of SAP ERP customers have transitioned to SAP S/4HANA, and another 12% stated that they’ve postponed their migration.
The reluctance is not surprising given the questions that come with a move to SAP S/4HANA. Choosing a greenfield (new implementation), brownfield (conversion), or hybrid migration tends to spark debate, as does the decision to go with an on-premise or cloud deployment. Some companies are ready to start fresh, while others have decades of data they want to bring into their new systems.
Then there are the challenges of actually migrating to SAP S/4HANA after decisions are made. Almost half of the respondents to the same survey point to defining the target architecture or roadmap and identifying dependencies among ERP systems as a challenge. Other companies find that custom code in their ECC systems, data migration and cleanup, having personnel with the right skills, and integrating SAP S/4HANA with other systems pose difficulties.
If you’re part of the 74% of companies still in the evaluation and planning phase of your migration to SAP S/4HANA, take some time to brush up on what you need to know before making the switch. We’ve scoured the Internet for the top 5 most helpful resources for companies moving to S/4HANA – bookmark this page and come back to it when you have questions.
