MyBB Community Forums

I have a MyBB Forum Database which I'd like to merge the users, posts, and topics into NodeBB. I looked into one plugin that said it'd do this but it didn't work. It had an API Error as shown below and I'm a loss of how to get my old members and posts imported. Even though it was never really a huge forum it'd be nice to merge our previous users content into the forums. The previous site was powered by MyBB 1.8.12.

I think you don't ask in the good community. If you're migrating to NodeBB, ask them.
Merging tools (and support) here are to merge TO MyBB.

Yes, we're obviously not going to assist you with moving away from MyBB to software we don't know anything about.
