How to transfer database data from MAMP to MAMP PRO?

  1. Stop all servers and close MAMP and MAMP PRO.
  2. Switch to the Finder, press cmd-shift-G (or select "Go to Folder") and type or paste "/Library/Application Support/appsolute/MAMP PRO/db/" and click "Open".
  3. Append "_bak" to any folder starting with "mysql".
  4. Open MAMP PRO and launch the servers.
