Upgrade

[Kazaf009]

I would like to upgrade my board from 2.3.4 to 3.0.0.
Would all the extra stuff that I added in the MySql database when installing hacks be deleted when I upgrade. If not, how do I delete all the extra stuff?

read the manual and get the mysql database conflict script to check if you will have problems.

I've read it and i couldnt find the answer, thats the reason I asked. Even if there is no conflict, I would like to delete them coz they will not be used with the new board.
