Decided to give it a go but not this site. I'll do the upgrade from 2.0.1 to 2.0.2 at my other test ground here.
By the way the 2.0.2 download is here the detailed instruction is here.
It is said to be a lot easier as there is no change to the database structure.
PS: It's now done, nice and easy. I have also activated the wp-shortstat plugin recently hacked for 2.0.2 by Pascal. I'll see if all my required plugins are working fine before I upgrade this site to the latest version.
PSS: wp-shortstat appears to be working and I have also upgraded UTW plugin to 3.1 there
