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.
