Specifically this following file contains the ethernet address of the previous host system and must be deleted in order to be created new with the new address of the new host system. /etc/udev/rules.d/70-persistent-net.rules Remove it before shutting down the old host server and it will be ready to boot on the new host server. WARNING! If you have multiple IP addresses then your server may not be accessible over the network due to swapped network interfaces unless you preconfigure the file correctly. But since you are moving disks I assume you have direct console access and so can make the configuration changes directly on the console. I would simply remove the file, move the disk, boot, then check that things are correct and swap them if they are not. After booting the new host server check that file and verify that the ethX device naming matches your desires. If there is only one network interface then it will by definitely. But often servers have multiple network interfaces and if so then they may be swapped from the desired naming and may not match static IP assignments, may not match firewall interface rules. Bob
