If simply to fix a typo or a mistake on a recently delivered release, then yes. You can simply edit the artist’s name in their artist section of your system, set your release back to “Edit” and update the linked artist and then “Save & Make Final” to update stores.
However if this is an artist wanting to change their name on already released content then we would advise that it’s not an accepted practice to change, remove or add artists from content already released. The songs were released by the artists associated and would need to remain as such.
In that case we would advise they only use their new alias for new releases going forward.
