These are my rough notes for upgrading to a new version of MAMP standard.

  • Rename /Applications/MAMP to /Applications/MAMP-old
  • Get the newest version of MAMP and run the installer
  • Copy over the site files in /Applications/MAMP-old/htdocs
  • Copy over the db files in /Applications/MAMP-old/db/mysql
    • The new directory may be called "mysql56" or similar instead of "mysql"
  • Copy the my.cnf file from /Applications/MAMP-old/conf
  • Edit .bash_profile to include the new paths
    • ie., export PATH=/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php/php7.1.1/bin:$PATH
  • Compare the following old files to the new ones and update as needed:
    • php.ini
      • There are two versions of php.ini for each php version. The one that you want is in the /Applications/MAMP/bin/php/(php version)/conf/ directory, ie., /Applications/MAMP/bin/php/php7.1.1/conf/php.ini
    • /Applications/MAMP/conf/apache/httpd.conf
    • /Applications/MAMP/conf/apache/extra/httpd-ssl.conf
    • /Applications/MAMP/conf/apache/extra/httpd-vhosts.conf
  • Copy over SSL server keys
    • cp /Applications/MAMP-old/conf/apache/server.crt /Applications/MAMP/conf/apache
    • cp /Applications/MAMP-old/conf/apache/server.key /Applications/MAMP/conf/apache
  • For newer versions of MySQL, run mysql_upgrade to upgrade your tables to support the newest MySQL features, see https://dev.mysql.com/doc/refman/5.6/en/mysql-upgrade.html
    • If you don't do this, check your MySQL errors log, ie., /Applications/MAMP/logs/mysql_error_log.err, and you will most likely see errors telling you to run the mysql_upgrade command.
  • After you are confident that the new install is working ok, delete the /Applications/MAMP-old folder
