A few days ago, after installing sp1 on my moss server, I saw that I can't run an upgrade for database that didn't pass the prescan without any errors.
I had this small database that I wanted to upgrade but god knows what a weird error I got on a certain website, that didn't have any special customization or any unusual data.
So I just wanted to get over with it, and move on.
I checked what is the difference between the sites that did pass the prescan, and dthen decided to do a small change in my content database...
Be aware, this tweak is NOT supported. But it does work.
So what you need to do ?
Change the 'bitflags' column in the 'sites' table in the content database so that its marked for a successful prescan.
If the prescan hasn't been running then value is 0 and after successful prescan the value changes to 262144.
