Description of issue

How do I remove the warnings for renamed casks?
e.g. I run brew cleanup and get
Warning: Cask homebrew/cask-versions/firefox-nightly was renamed to firefox@nightly.

I've tried to uninstall and install again but because of the rename it doesn't find firefox-nightly

I've tried brew migrate firefox-nightly

Relevant casks

firefox-nightly

[SMillerDev]

try brew upgrade firefox@nightly
