new disk installation

Hello guys I have an old system running SuSE 6.1 and i want to add a new hard disk (40GB) and transfer everything from the old disk to the new one with the same distribution How can i do this? Probably i will run fdisk /dev/my2nddisk but after that what? I mean how i can transfer all the settings from the old disk to the new one without loosing any data? Thanks a lot
