The hub mesh documentation doesn't seem to include much information about the "Update" (hub swap) feature in hub mesh. I am beginning my C8 migration and I want to ensure I do things in the right order so that I don't have a huge mess on my hands.
My current setup:
Hub1 is a C5 with a C4 USB radio, and is used for all z-device connectivity
Hub2 is a C7 that I use for all of my apps and most of my automations
Hub3 is a C8, which I intend to replace the C5 with, after manually migrating all of my devices to it.
I restored a local backup of the C5 to the C8, in order to retain all of the device names.
I renamed the name and DNI of all of the z-wave devices on the C8 to avoid a conflict.
Here are my planned steps:
Disable z-wave radio on C5
Migrate all z-wave devices to C8 manually
Use App Swap feature to swap the device names from "old" to current in the C8
Migrate all zigbee devices to C8 manually by removing from C5 and adding to C8, in hopes that they will appear as an existing device and reuse the name/device ID that was restored from the backup.
Now comes the hub mesh part...
Do I need to "link" the devices on the C8 to the C7 prior to doing the hub mesh "update" on the C7? Or do you do the update without linking the devices to the hub? They currently show up as "available" devices (not yet linked) on the C7.
Are there any special provisions I need to make for the old/new z-wave devices before updating the hub mesh? I planned to do the app swap to get the "real" z-wave devices into my apps, and then force remove all of the "old" devices from the C8. I wasn't sure if I should update/swap the hub before or after this part of the process.
