Is there a way to rename a branch?

[Rolf Marsh]

I apparently have some branches out of sync; is there a way to rename a branch?

[Mikael Sandberg]

You would need to do the renaming locally in your repository. But before you do that, delete the branch in Bitbucket, do a fetch in your local clone to update it (if doing it from Sourcetree, make sure you check prune tracking branches, from cmd use git fetch -p). Then you can rename the branch and push it back to Bitbucket.
