I remember running a Raiser's Edge server in the Noughties. Geez, what a piece of work. If memory serves, Blackbaud came out with a new set of patches every Friday to fix the bugs they'd introduced in the previous Friday's set of patches. As soon as we got wind that Blackbaud was offering RE as a hosted-solution, I went straight to the Alumni/Advancement VP and said "yeah, you need to do this, no matter how much it costs." They did, and my Fridays became a little happier.
