I recently purchased a MacBook Pro 13" with the M1 chip and transferred all my data over using a Time Machine backup. Homebrew packages are currently installed in /usr/local/opt/ but it is my understanding that they should be under /opt/homebrew for Apple Silicon Macs.

How can I:

1. Get the list of packages I currently have installed
2. Remove those from /user/local/opt
3. Reinstall them under /opt/homebrew

I kind of assumed Homebrew would be clever enough to do this automatically but apparently it needs some manual maintenance. Thanks in advance!
