Remote suse install

Hi everybody, I hope this question does not sound too stupid. I have several Suse Linux servers, and each time that I want to upgrade, I have to run around with a pack of cd's. I would like to copy the CD's to one machine, and install all the others from there. I'm am sure this is possible, but since I'm a newbie in this area I don't even know where to start looking. I would appreciate it if anyone can point me in the right direction. Thanks Marius
