I have had Obi100 for many years using GV. Two years ago I got the obi200, unplugged the 100 and put 200 in place. It worked right out of box. I changed nothing on Obi dashboard as it still shows 100 as being offline but everything still works fine. Should I worry about this and maybe try to set up new on Obi or leave as is. I'm concerned because I want to change my GV number and want everything to still work. Suggestions?
