The basic steps are that you just install the new version over the top of the old version to update it. Your customization should remain intact (not affected). However, if you have important settings that you don't want to lose, then it's a good idea to back them up first.
Backing up keyboard shortcuts:
Use the "Export" function in Keyboard Preferences. See: https://manual.audacityteam.org/man/key ... ences.html
Backing up Macros:
Macros are stored as text files, one for each macro. You will find them in the hidden folder:
where "<user-name>" is your user name.

Either way, you need to export your custom curves.
Audacity 3.0.0 includes a tool that can convert the older "Equalization" settings into "Filter Curve EQ" settings. See: https://manual.audacityteam.org/man/eq_ ... erter.html

You can just copy those three files to somewhere else as a backup.
The quick way to backup just about everything, is to simply copy the folder:
but it's useful to know which bits in there do what.
