I could not find a specific request page for nominating movement of releases that have been incorrectly labelled. There are many releases that are under “Marshall Cavendish Partworks Limited” — which is the publishing company that issued magazines with accompanying CDs in the UK and elsewhere. The correct label IMO should be Marshall Cavendish, the imprint. This is the case with discogs. What is the process/form/page for nominating bulk movement and merging of relases?
None to my knowledge, you’ll have to edit all releases, I guess.
Is there a way to transfer MBIDs?
If all releases should be moved then the quickest/easiest/laziest way to do so would be merging the two labels and re-create “Marshall Cavendish Partworks Limited”, but then it would have a new MBID.
