I'd like to get started with my ISSY => EISY upgrade, but I might need to do a bit in a day, and then flip out to my ISY for a day or two, doing this until I get things to the point where I can set the EISY to production.

I know I have to be careful not to have them both on at the same time, but is it OK to plug one system in during one day (EISY), do some work, such as upgrade the firmware, and tested download, and then at the end of the day turn the EISY off, unplug the PLM from the EISY, and then connect the PLM to my ISSY, and use it for a day or two, etc.?

I also have a spare PLM, so am I better to plug it into my EISY, use that pair, each on its own system?

I have experience moving the plm from one system and back to another. Have to be careful not to change anything. I'd find a way, a time to make the conversion one time

DO NOT TRY TO USE 2 PLMs with the same Insteon network. "There can be only one" controller owner of an Insteon network
