Today I did a test move of our development linux server to another machine. It took me less then two hours to do so, considering about 7 GBytes of data, and difference in hardware (Compaq machine and IBM machine). I have used tar, netcat and Red Hat Linux 7.2 disk. Everything seems to work find, except for Microsoft DNS server loosing track of the machine and generating some random junk. Tomorrow I will move few more servers.
