dist-upgrade sarge to etch

[sigi <dugongs@gmx.de>]

Hi, 

some days ago I had to reinstall my system, and I chose debian sarge to 
install on it. Now, I liked to have more recent packages on my machine, 
like I had before. 

I tried a 'apt-get dist-upgrade' but this wants me to uninstall nearly 
my whole gnome and kde stuff... totally over 300 packages. 

Is this normal, and I should reinstall this packages, after the upgrade, 
or is there sonething wrong with this? 

In my sources.list I only have the 'official' mirrors listed, up to now: 

deb http://ftp.de.debian.org/debian-amd64/debian/ testing main contrib non-free
deb-src http://ftp.de.debian.org/debian/ testing main contrib non-free

Is there something wrong here, or should I risk this upgrade?

Regards,
sigi.
