C7 -> C8 v 2.4.4.129 migration, hub mesh

Didn't know where else to post this. Migrated a C7 to C8 Pro. Hit a few bumps but we're up and running now. Considering using the C7 to host my Internet-facing apps (OpenWeather, some web page scraping) in a hub mesh to take that load off of the C8 and provide some app isolation. The sync between the hubs is not time-sensitive, so data from the web-facing hub (C7) syncing to the C8 to provide data for the Webcore pistons on the C8 can proceed at a relatively leisurely pace.

The C7 is off-line right now, but I suspect still has all of the existing devices registered, duplicating what is registered in the C8. I don't plan on sharing any devices between the meshed hubs, just data via hub variables.

Question is: will a full factory reset on the C7, then bringing it back on-line (in the same network segment), allow me to cleanly set up the mesh? Or can I just bring the C7 back on line and remove the devices and disable the radios since I won't need the C7 to talk to any of the devices (device communication will be exclusively handled by the C8).

Or, am I just overthinking this (wife's observation, but possibly valid)?

Reset the hub, install the apps/devices. Share. Make sure they are both on the same segment.

I think you are overthinking it. I highly doubt you will have any significant load to take off of the C8 Pro. How loaded up was your C7 you migrated? My 100s of devices and tons of constantly busy apps have not overloaded my C8.

I would run everything on the Pro for a bit and look at stats, you probably won't really gain anything but a pain in the mesh by running two hubs together.
