Have just updated both units in my 440 Pro CI configuration. A word of caution or just confirmation from those who have upgraded dual units.
I used one SD card to try and update both. For some reason, after completing the upgrade of the first unit, I placed the SD card in the second unit and it wouldn't upgrade at all. Just went into Factory Config default mode on startup as a separate 220 unit.
To solve, I had to copy the files completely again to the SD card from my computer. Then placing it in the second unit finally kicks off the upgrade process. There's a file that gets erased, apparently, after you use the SD card once to upgrade a unit. (I believe it's fw.txt but I could be mistaken.) So the list of files required for the upgrade is incomplete after using it once already for an upgrade.
