Does intalling Lion wipe data?

I am keen to upgrade (I have an i5 MBP 13" - April 011).

Once installed will the following remain intact:

Email Accounts

User Accounts

Internet ISP Accounts

Drivers for Hardware

Bookmarks

Appreciate any guidance from those who have upgraded already!!

As long as you have a Time Machine source connected, it will ask you what you want to restore during installation

The correct answer is: yes, the simple upgrade that occurs when you buy Lion, download it from the App Store and run the installer to upgrade, keeps all of your current data.

The above answer would only apply if you were to wipe your drive and do a clean install.

As always, you should have a backup prior to upgrading the OS. Things can, and do on occasion, go wrong.

I didn't have to do anything after confirm installation with a dialogue box. I left it to paint my door, came back about 30minutes, Lion was installed ready to go. One of the easiest installation of OS. All user preferences, bookmarks, files, etc. stayed the same.
