Logic Pro 9 Delete 9.0 to free up hard drive space?

[BarryCahill]

I recently downloaded and installed Logic 9.1.1 (It was a BIG file, about 875 meg). Can I now delete/uninstall Logic Studio 9.0 to free up hard drive space, or is 9.1.1 an overlay that requires the original?

I believe you can, however why not just back up 9 to a CD, it should fit. There may be a bug which surfaces that requires you to temporarily go back to 9.
