overriding old tag (move tag to latest commit)

overriding old tag

Use the -f option to git tag:

-f
--force

    Replace an existing tag with the given name (instead of failing)
You probably want to use -f in conjunction with -a to force-create an annotated tag instead of a non-annotated one.

Example

Delete the tag on any remote before you push
  git push origin :refs/tags/<tagname>
Replace the tag to reference the most recent commit
  git tag -fa <tagname>
Push the tag to the remote origin
  git push origin master --tags
