Featured Artist in the Wrong Field

This one is kind of hard for me to figure out and I'm not sure where to start.

I have some files that have the featured artist after the the song title in the TITLE field. I'd like to cut " feat Some Random Artist or artists" from the TITLE field and append it to the artist name in the ARTIST field. How do I go about doing this?

Jeremih / Don't Tell 'Em feat. YG

Desired Result:
Jeremih feat. YG / Don't Tell 'Em

See there ...
Move "Featuring" from Artist to Title
" (feat.) " problem

Thank you. I am not sure why I had difficulty find the threads maybe I wasn't searching right.
