If you’ve recently taken advantage of the Black Friday 50% offer for MAMP PRO, and contextually upgraded to the latest version, chances are that the automatic move of the databases didn’t really happen.
So you are probably scratching your head to move your hosts from MAMP to the MAMP PRO app. MAMP PRO documentation offers a hint on this page. However, there is one tiny detail missing that makes the difference.
Once you copied your database (copied, not moved) from
/Library/Application Support/appsolute/MAMP PRO/db/mysql56 you need to open MAMP PRO, start your servers and select
Tools > Upgrade Databases.
Also please note, that the path to the new database files is not referring to the Library in your home directory. It’s the main Library that you can find at the root level of your hard disk.
