"Right" way to update KDE

[Alan Dayley]

I have RH 7.1.  I need to update my KDE desktop to 2.2.1.  I did it once by 
installing the RPMs using the --force option but things got wierd.  Apps not 
starting completely, odd errors, other stuff.

Anyway, I went back to the original KDE 2.1.1 but now my KMail archive, of 
which I made a backup, is not compatible with this previous version of KMail 
(DOH!).  So, I need to move forward.  But this time, I want to do it without 
the --force option on RPM so I am confident all the dependencies, etc. are 
correct.

Anyone out there have some advice or know of a good HowTo?
