Wiki is something you should have a local copy of.

That said, GitHub wikis are just git repositories. You can clone them like this:

As for issues, it's only a little bit trickier - you'll have to use GitHub API, like this:

https://api.github.com/repos/hotsh/rstat.us/issues (from https://www.quora.com/How-can-I-export-backup-GitHub-issues)

I didn't know that. You still have the problem of mapping the user authentication though. Moving a big repository and giving users the right permissions seems pretty tricky. Do you know of any successful migrations away from GitHub?
