Anyone moved from IngramSpark to KU?

For the last week or so I’ve been trying to research how to go about moving my ebook from IngramSpark to Amazon so that I could turn it into a Kindle Unlimited title. I don’t get much traffic on my ebook, so I thought I wouldn’t be losing anything by pulling my ebook off wide distribution to try kindle unlimited, but I’m scared to do this until I know exactly what I’m doing. Unfortunately, I’ve not found a lot of information on how exactly to go about this or if it’s as simple as stopping distribution on Ingram and reuploading on Amazon. (I’m worried about messing up listings, reviews, etc)

Does anyone have any experience with this or have any resources that could walk me through the steps for as smooth a process as possible? Thank you!
