Do I need to change the IP on a restored backup?

Since you restored a backup, then your linux will have the old IP address.

If you have a static configuration and disabled network helper, then the server will probably be inaccessible once it boots (but will not affect the production server). You will need to use the LISH console to login and manually edit the static configuration for the new IP address.

But, if you have network helper enabled, then maybe the new server will boot with the new IP address configured properly. But you may still need to make manual changes to any custom software or daemons that are configured with the old IP.

I say give it a try and boot…. what could possibly go wrong? :D

Thanks for the reply…that helps. Looks like network helper is turned on for both the Linodes. Still going to wait until off hours to boot it up though :P
