The advantage with OEL is that most proprietary software supports OEL out-of-the-box, you don't have to do "naming" tricks to run software like SAP. Switching to OEL is quite easy (https://github.com/oracle/centos2ol) and the same method could be used to switch to something else if better options are available. Kind regards Thomas
