Cannot migrate the last few repos to

I want to migrate my GitHub phplicengine/bitly from to .com, I tried so and noticed all my GitHub repos are migrated from GitHub to except phplicengine/bitly. Why I cannot migrate/install this repo to .com? I even could not do this by doing “Manage Repositories on GitHub.”
please advise. Thanks,

Here are the links:

Check . Is that repo listed?
