When you are an SAP ERP customer today, and you want to quickly start your digital transformation, would you rip out and replace the backbone of your business, just so you can say "I run in the cloud"?  I didn't think so. But you would look at areas where you could make your existing investments in your SAP Business Suite more valuable by extending some business processes into the cloud, as you are evaluating how to move forward with SAP S/4HANA as the future digital core of your business.
