[ILUG-BOM] Upgrading Sarge to Etch

Hi!

I am finally able to install Debian Sarge (3.1) on my system. Here is the system config

MoBo: MSI - K8MM-V CPU: AMD Athlon 64 3000+ MEM: 512 MB HDD: 40 GB Mextor SATA CD/DVD: Samsung Combo

Now I am thinking of upgrading the Sarge to Etch.

Added following repository to source.lst

deb http://mirrors.kernel.org/debian etch main contrib

done

# apt-get update

Now

# apt-get upgrade

Tells me it will download 75 (71.8MB) upgraded packages

# apt-get dist-upgrade

Selects 737 upgraded, 345 newly installed, 55 to remove and 2 not upgraded and will download 667MB. :-(

Do you think my system will survive this upgrade?

Is there any way I can selectively upgrade only important packages like X11?

TIA for your help and support. With regards,
