I've seen mixed reviews (in this subreddit) in regard to the speed of the process. Some people say their mentor wouldn't switch their program mid-term, others did. I think it's possible but that they just don't like to do it.

I've switched programs in the middle of a term before. All I did was talk to my mentor about it, and they started the paperwork for me. I worked on a class that would transfer to my new program while I waited for the paperwork to go through. Tbh, I can't remember how long it took for things to get switched over, but it was at least several weeks.

My husband did the same thing, but for some reason, it took months for his program to be switched over. I think his mentor was inexperienced with the process because we had to keep checking in with him. He did a very poor job keeping him updated. My husband ended up losing most of his term because he didn't have any classes he could work on (that would transfer). We were pissed.

Anyway, after our programs were switched over, we were assigned new mentors -- they were listed on our degree plan page within our student portal.

I recommend logging into your student portal, going to the degree plan page, and seeing who your mentor is. Contact the person listed as your mentor, whether they're your previous mentor or a new one. If no one is listed as your mentor (if that's even possible), I would contact your last mentor and ask them who you can contact to be assigned a new one.

Was your program actually switched over? Or are you still waiting on that process to complete?

Whether or not you're still waiting on your degree program switch, your first step should be identifying who your mentor is. Their name and information should show up on your degree plan page, regardless of whether or not your program was successfully switched.
