Keep a backup copy of previous versions of Logic Pro

It's always a smart move to keep a backup of Logic, giving you the flexibility to revert to a previous version if needed.

1. right-click your current version of Logic and select "compress Logic Pro."

2. Wait for the ZIP to be created.

3. You can create a new Folder with the Version number of Logic to avoid confusion

4. Drag the ZIP into the newly created folder.

You can do this as many times as you want each time you update Logic.
