I have my web development environment on a mac pro running on OS X version 10.6. I'm considering upgrading it to Mac OS X 10.7.

Will it upgrade smoothly or do I have to reinstall mysql, perl and so on? I am especially scared for upgrading MySQL and the databases.

To answer remarks here below, I don't remember how I installed MySQL in the first place, but for what I remember, it didn't came out of the box. That's why I am scared it might get removed.

Concerning the os version, I tend to say as close possible to the version that came with the mac at the time. The more recent the OS the more resource hungry they are. I prefer to have a fast mac then an up to date OS. I would stay to 10.6, but there are some applications could help me and are only running on 10.7.

Is your current MySQL compatible with Mountain Lion? – Rob Feb 4 '14 at 12:32
How did you install MySQL - also what is your reason for upgrading and why not directly to 10.9? or just leave at 10,6 – Mark Feb 4 '14 at 13:41

Usually my MySQL installation works after upgrading. You may want to review your php.ini to correct the position of the MySQL socket (php.ini gets changed by the upgrades). – pietrodn Feb 10 '14 at 9:34

MySQL, as well as the databases, is still there and working after upgrading. This said, all the settings, php, mysql, apache, virtual hosts, where resetted to the default. Very annoying I have to rebuild all my development environment.
