Note that any time you literally clone a system, you'll need identical HW or you may face HW driver issues.
If you have proprietary drivers installed, or are using a specifically tailored kernel there could be some issues to address.
In most cases, no problem at all.
I normally just delete the /etc/udev/rules.d/70-persistent-net.rules so that the network interface remains eth0 (rather than creating a new eth1 etc) and change the hostname and ip if appropriate.
