Migrating from x86_64 to arm64 Homebrew

[JordanField]

Hi all,

Fantastic work getting Apple Silicon working!
Apologies if there's a guide for this somewhere, but I haven't found anything.

I want to:

1. Install native arm64 brew
2. Collect all formulae (but not casks) installed via x86_64 brew (henceforth ibrew, since that's the alias I use to run using Rosetta)
3. Re-install these formula using brew
4. Remove the Intel formulae
5. Remove ibrew entirely.

What is the least disruptive way to do this? Thanks in advance 😄
