I think most people who purchase a new Razberry 7 board will use the new board to replace an old board. In a very real sense, the procedure for migrating to a new Razberry 7 is the same procedure as dealing with a Razberry board that has had a hardware failure - the desired outcome is to make the new Razberry a clone of the old/broken Razberry. This means the new Razberry will have the same Home ID and Node ID (presumably ID=1) as the old Razberry. Note that you cannot use both Razberry's at the same time on your network since they both have the same Home ID and Node ID. The benefit of cloning is that your Z-Wave devices will not know they're talking to a new controller, which is important for retaining Lifeline associations that only report to Node ID=1. You can still use your old Razberry as a secondary controller on your network, but you will need to do a Controller Factory Default (via Expert UI) and then include it using your new Razberry 7 (on your old Razberry, select Include into Network). Following this procedure, your old Razberry will be given a new Node ID (not ID=1) and the Z-Wave network should operate correctly.
If you simply add your your Razberry 7 as a new primary controller, it will not be assigned Node ID=1 which will mess up any associations your devices have that use Node ID=1. In most cases, this is a significant problem which is why the backup/restore cloning approach is recommended.
