Need help on updating Orbi RBR40/RBW30 firmwares

I just wanted to report back.  Everything went well.  Steps taken were as follows (to help myself in the future, if needed):

1. Disconnected the router base from my modem so that it had no internet so that the router base wouldn't automatically update itself while I'm trying to update the satellites first.
2. Over wifi, logged in to the router and manually downgraded the firmware of the router directly from 2.3.1.44 to 2.2.1.210.
3. Had to unplug and replug in the satellites to their electrical outlets to get them to change from "Waiting for connection" to "No internet" so that I could update their firmwares.
4. Updated the firmwares of the satellites (one at a time for my own feeling of comfort) directly from 2.2.1.204 to 2.3.0.4.
5. Updated the firmware of the router base directly from 2.2.1.210 to 2.3.1.58.
6. Plugged the router base back into the modem.

Internet is up and running and statuses are good on all 3 devices.

Thanks for the help, Furry!
