I have made a tag in mercurial:
hg tag release_123
Later on I found out that the name was wrong, it should be release_124. Is it pos
release_124
I've been looking for a solution to same issue: I found this command which creates another tag with copied from the previous one with a new name. But it does not remove the old one. It has to be deleted manually.
Rename a tag :
hg tag -f -r
To delete the old tag:
hg tag --remove
