Tips For Your Upgrade

Settings

Your host settings will be unaffected by an upgrade of MAMP PRO. It is never a bad idea to back up your host settings. You can do this using the File > Backup …  option.

Host Files

When MAMP PRO is upgraded, the current Applications/MAMP folder is renamed to Applications/MAMP_X_XX.

Your default host, localhost , is located in the Applications/MAMP/htdocs folder. This is a convenient location for your default host, residing in the MAMP directory. When MAMP PRO is updated, your default host location (Applications/MAMP/htdocs) files are automatically moved from your original Applications/MAMP folder to your new Applications/MAMP folder.

It is recommended any additional hosts reside outside the Applications/MAMP PRO directory. A recommend place to keep your additional hosts would be in ~/Documents/Hosts/ [Host1, Host2, Host3 …] folders. This will keep your host files separate from the main MAMP directory. 

Saving your host files outside of the Applications/MAMP folder will save you the trouble of moving all your host files over to the new Applications/MAMP directory every time you upgrade.

Database Files

Your database files reside in /Library/Application Support/appsolute/MAMP PRO/db/mysql . Your database files will be unaffected when you upgrade MAMP PRO. 

It is always a good idea to keep backups of all your host and database files before upgrading.
