Can I Transfer a Release Between DistroKid Accounts?

No.

At this time, we're unable to move songs between DistroKid accounts.

However, we are happy to redirect earnings from one DistroKid account to another. 

To do this, use DistroKid's "Splits" feature to redirect 100% (or any percent of) earnings from the chosen track(s), to the new DistroKid account.

This ensures that metadata, stats, playlist placements, ISRCs, and everything else remains unchanged.
