Indeed, the information needs to be the same. In this specific case, the posts would have had the same IDs, so if I would have been able to just grab the post ID from the start, it would have been easy. I’m not going to detail the whole process I had to go through. It wasn’t pretty, and there definetely would have been a better way for the whole thing to go down. Sometimes, that’s just how it is.
What I find strange though is that ACF stores an ID number for Page Link fields, but outputs an absolute URL. And that WP All Import grabs the retuned value. It might be using ACF functions (get_field()) to return the value instead of grabbing it directly in the database?
