Yes, if your harmony remote is working, it is much easier to change the address on the other remote. To change the harmony remote, you would either have to find a complete set of commands on the harmony website for a different address, or change the remote address and then manually enter them into the harmony. The harmony doesn't have "addresses" like the dish remotes. The only reason that there are dish 6000 commands on the harmony website is that someone previously programmed them all for a dish remote set to address 1.
