I've been going through this, trying to move an app from a corporate account to a personal account. Could not transfer because it used CloudKit. First try was to just build the app on the new account - Apple rejected it as spam, probably because they figured out it was similar to the app on the corp account.
DTS said basically to delete the old app, then quickly grab the name for the new one.
For now, I've built a "premium" version of the app without CloudKit on the corp account, will try to migrate users there, then transfer that new app. I'll be back to let you know how it goes.
