Will definitely keep same IP then. thanks!
Give it a different name, though. Some interfaces use the name rather than the serial number.
BTW: When you restore the backup, your new Vera3 will inherit the root password from your Vera Lite. So if/when you connect with SSH, puTTY, WinSCP, etc, use the old password and ignore the one printed on the V3's label. If you use the same IP address for the V3, WinSCP sessions for the Vera Lite will still connect to the Vera3.
