How to perform non-clean install from Lion>ML?


Does ML give the option of a non-clean install where I do not have to reinstall all my apps and settings and data. eg. in-place upgrade like in windows? Anything I should watch out for before upgrading? I have a March 2010 13" Macbook Pro core 2 duo 7,1.

I am out of town and would like to install ML on my secondary hard drive on my macbook pro but don't want to have to delete everything?

Is this possible as is it dangerous?

I would like to play with ML before going home next week. Thanks.

You can download it from the MAS and just let it install as an in-place upgrade. Doing a clean install involves doing slightly more.
