Update music track

Hello! I want to update the music track in full version and 30sec. version. I have sales for this track. And they are growing. I improved the arrangement / mixing and mastering. How can I just update a music track? Thank you!

I have also recently remastered my recordings and have various versions of them I would like to upload. Can we just replace the audio with the new one? It would be tedious to redo all the tags and descriptions. Please share
