Upgrade from prefinal to final Backtrack 4

[Herztier]

Hi people !

I've got prefinal persistent USB installation of Backtrack. Do someone knows how can i upgrade from prefinal to final persistent USB without messing all the settings i already have (don't want to complete reinstall)

Thanks !

i dont know if its possible or not but i would definatly reccomend just starting from scratch. if u update it might break some things. but i could be wrong.

You will need to do a clean install.

A clean install will go smothly. if you try to upgrade and don't know what you are doing something will go a miss and won't work.
