I have an old server ( Red Hat Enterprise Linux ES release 2.1 (Panama) ) that is in desperate need of replacing, is it possible using dd / ssh to clone the server onto a Rackspace VPS? Or more precisely after the server is cloned what problems can I expect e.g. booting etc?
I have successfully used this command (found in another serverfault question) to clone one vps to another:
dd if=/dev/sda | gzip | ssh root@target 'gzip -d | dd of=/dev/sda'
but that was two machines of the spec.
