I figured out how to migrate a GitHub wiki (public or private) from one repository to another while preserving all history.
The trick is that GitHub wikis are just Git repositories. Which means you can clone them, edit them and push them.
This means you can migrate them between their parent repos like so.
myorg/old-repo is the repo you are moving from, and
myorg/new-repo is the destination.
git clone https://github.com/myorg/old-repo.wiki.git cd old-repo.wiki git remote remove origin git remote add origin https://github.com/myorg/new-repo.wiki.git git push --set-upstream origin master --force
This will entirely over-write the content and history of the wiki attached to the
new-repo repository with the content and history from the wiki in
