I consult on Oracle ERP software who are attempting to transition customers from their legacy, on premise (EBS) system to their hosted / managed SaaS (Cloud) offering. Main issues are:

1) Lack of customization options - in Oracle's case, their Cloud offering is hardly customizable (no database access) compared to the on prem version. Thus, key functionality is lost which makes running a business difficult.

2) Cost - you basically need to re-implement your business, which is a $1MM+ affair and tons of time and risk and consultants and work for your team. Plus the Cloud solution isn't that much cheaper in the end.

3) Bugs - the Cloud software is new and still has many problems. Let someone else fight those.
