I would expect you would have problems. For example, the network admin dashboard only runs on the main site. If you make the main site mapped to a sub site then you would get a redirect loop whenever you attempted to access network admin.
Hmm ok it looks like I should take the route in these instructions instead: https://askwpgirl.com/move-wordpress-from-subdirectory-to-root-directory/
The section called: “Displaying WordPress URLs from root directory when WordPress is installed in a sub directory” instead.
Hopefully it won’t create the same problem…
I’m about to follow the same instructions (moving index.php to root while leaving the WP sub-directory in place). How did these instructions work out for you? My second option is using the Duplicator plugin, but the askwpgirl instructions look simple enough to employ. Thank you!
Any updates guys, how did the https://askwpgirl.com/move-wordpress-from-subdirectory-to-root-directory/ process go? Having the same issue. Massive site which is better left in subdomain/folder. Any response and pointers are most appreciated. Thank you in advance!

So if I remember correctly, this did work. I was actually working with a multisite so I cloned the dev site into a subsite of the main site. I followed the instructions, I just had to choose the new template files on the pages and clean up a few random odds and ends with the css or anything which didn’t fully import, check the urls, and it was all good.
