Jumping from BAAN 4 to LN

I am considering moving BAAN 4 to Infor LN and I have a couple of question that I hope someone could answer:

- From an ERP move standpoint: when evaluating to move from BAAN 4 to Infor LN 10.7, should we consider this as a technological upgrade or as a fresh conversion to a new ERP system. In other words, from an effort perspective, moving to LN is the same as moving to ERP XYZ or is it a simpler road.
- From an end user change management perspective: Beyond the graphical interface, are the main business processes and data flows in LN 10.7 comparable to the ones in BAAN 4?

I appreciate any feedback.

Thanks in advance
