Guidance on duplicate changeset ids

I’ve inherited a repo (fairly new, not a log of changesets) that uses duplicate changeset Ids (for different tables). What is the guidance on this?

  1. should I rollback and re-create with different changeset IDs? I do see that “A changeset is uniquely tagged by both the author and id attributes (author:id ), as well as the changelog file path.” Changeset
  2. Just leave it and continue adding change-sets with unique numbers.

Are there any cons to leaving duplicate changeset ids in changelog if changeset is uniquely identified by author id and filepath?
