And just for this reason it is not recommended to try this. You might 
get a system that runs, but you are not sure what exactly you have got. 
And one of the days you get strange problems that can not be reproduced 
elsewhere. We do not support such systems, and if a user that had done 
that form of upgrade reports a problem we tell him to properly 
re-install his system first.

Perhaps they are, perhaps not. You waste much more time debugging 
strange issues than you gain by doing a proper install. So why take the 
risk?
