Thank you!

Let's add an additional test that runs the migrator on a feedstock and make sure the pinnings repo is setup properly. Then we should be able to merge!

@beckermr Is there an example for one of the other arch migrators that I could copy?

[beckermr]

Not specifically for an arch migration but there are good examples in tests/test_migrators.py.

No piggy back migrators?
