Does reinstalling a new version of Xcode automatically overwrite the old?

e.g. I had xcode 3.2.5 and I downloaded and installed Xcode 3.2.6 (including ios). Does the install overwrite and get rid of all the xcode 3.2.5 data (assuming it doesn’t use any of it)? Thanks!

    Yes and no. It will overwrite files in /Developer/usr, /Developer/Tools, /Developer/Library, etc, but if a file already exists that the new Xcode install does not have an upgrade for, the installer wont touch it if it doesn’t have to. Personally, I have found that the best way to upgrade Xcode is the following:

    1. Backup the working /Developer directory (where the “old” Xcode is installed)

      [ 15:30 jon@MacBookPro / ]$ sudo mv /Developer /Developer-3.2.5

    2. Run the “new” Xcode installer using the default install location (/Developer).

    This way you have everything from both and can merge the files you need.
