How many times can i assign DOI again?, i have changed the metadata.
It is advisable to only assign one DOI and update the metadata and resubmit this the repository you’re using.
If you’re using Crossref, please refer to the Help updating metadata page.

Im asking this, just because i have changed the authors´s names in the articles
In that case you should not assign new DOI, just update the metadata of the existing DOI.
