http://forums.cpanel.net – Hello all, I've got to transfer my server to a new hardware, the hard drives will change, even the volume of those drives will change .. i was wondering how can i migrate without having to go through the headache of re-configuring everything, i did some search and everyone was suggesting new installation on the new server and then moving the accounts using WHM, but i have made considerable changes in my configuration i would really like not to repeat all that again, so it came to me i could use dd to clone the drives from a rescue DVD so i have 2 questions here: is this method recommended?
