Conclusion: Many organisations have integrated enterprise architecture (EA) into the business processes, whilst many have not. To some, it is a religious argument as to why the ICT group even needs to have people with ‘architect’ in their name; for others, the EA group is the watchdog of the system, ensuring both new capabilities and changes to existing capabilities will be fit for purpose.

Conclusion: SAP ECC on-premise versions required ownership of ERP infrastructure and multi-year licensing. The business cases for such investments considered ERP systems essential to remain competitive in IT service industries, logistics and resource-intensive sectors.

Even with this infrastructure saving, the data migration risk remained with CIOs looking to identify a reliable data migration method. Any data migration considered to be high risk should be avoided in the current environment. Many are unfamiliar with the best method to migrate from on-premise SAP solutions to SAP S/4HANA in the Cloud.
SAP and its partners are now making this data migration journey not only more transparent but achievable in a timeframe that is measured in months not years. This is being achieved through Cloud platforms that can interrogate and integrate legacy data, then present migration paths in real time whilst retaining the data integrity before, during and after the migration.
