I have one on going ticket with Numara on the upgrade... it started with the initial ticket about projects not showing up. It has evolved to a whole list of other problems that keep coming up. We are gradually getting through the problems, but it is taking some time. A lot more time than I was anticipating on the whole upgrade process. It is fine, but it is taking focus away from other tasks and projects that I need to complete.
Overall, it has not been a bad process. I think we caused the problems partially ourselves. We waited for years to upgrade to the current FootPrints version which caused migration issues with the database and the data. We will get through the steps and resolve the issues... it will simply take some time.
