I'm planning to move a hard drive from one server machine to another. The hard drive is an IDE drive. The motherboards are different, as are the memory and such. In this instance, graphics isn't a problem because this is just Ubuntu Server.
Are there any precautions I should take, or steps I can do beforehand, in order to make this go as smoothly as possible? I've of course already backed up /home directories and configurations in /etc and /var.
