That’s a good point. However, some of the instructions below specifically tell people how to force any channel onto using the existing Release profile. I’ll update my post.

And I told the developer edition to use my regular profile because that's the one that has all my settings and add-ons and I didn't realize the risk was there. Guess at this point all I can really do is hope and cross the bridge when I get there.

If you’re on Mac, you should be able to recover the old profile with time machine. Or if you are on windows and have another backup setup.
