Hi @lgutierrezc. Welcome to the Crossref community forum! Thanks for posting.
DOIs are intended to be unique - that is one DOI per content item. If we (you) follow that rule, it prevents multiple DOIs from being out in the world. Those duplicate DOIs create: a) manual work for you and me (Crossref); b) compounded content registration fees for our members who are registering these duplicate DOIs; and c) most importantly, citation splitting for those duplicate DOIs (e.g., when DOI A is cited by researcher A and DOI B is cited by researcher B). Said another way, having two separate DOIs for the same content means researchers won’t know which one to cite, and this risks splitting your citation count.
So, the idea of a new DOI for the content should be avoided. You can update the metadata that has been registered for this DOI so that it is current, but you should not publish or register a secondary DOI for the same content item.
Please let me know if you have any additional questions.
