Of course, you can!
To ensure a smooth transition, we suggest starting by uploading your release with us before removing it from the other distributor.
Additionally, if you provide our support team with a screenshot of your take-down request, it will speed up the review process.
You can also reuse your old ISRC codes for your new release on Record Union. Simply enter the codes in the ISRC code section for your new release, and you'll be all set.
Using your old ISRC codes will make sure that the public play statistics on Spotify will stay intact.
