Awesome job guys, earlier this evening I migrated my lighting C-7 hub to my new C-8, and it just works 
. There are only a couple of minor things I thought worth mentioning, more so for future migrations such as these, and perhaps for onboarding new customers onto the platform.
Hub Name - It would be nice to be able to seamlessly transition the hub name from the old hub to the new, my new C-8 ended up with HELIGHTS01(new)
Hub IP - It may be worth mentioning earlier in the process the potential need to replace any HE Hub IP Reservation in a router with the new C-8, i.e. removing the old C-X reservation and replacing it with the new C-8, if that is the intended outcome.
Expected Automation Triggers - Another step that may be worth inclusion is to assess prior to the migration any automations that are likely to fire during the migration and come up with a plan for how to deal with each automation, whether it be manually triggering the automation or some other course of action. My example was turning on some outside lights at sunset.
Daylight - On the subject.... Another nice to have... it may be beneficial to some users if the migration is arranged (by them) to occur during Daylight hours, or based on some other criteria. This can avoid unnecessary darkness.... Particularly useful during upgrade.
Video vs Documentation - The video (tutorial) seems to cover the basics of the migration, offering a good illustration of the overall ease of the migration. But the documentation was ultimately what I needed to refer to for the more complete set of steps. While I like the convenience of a video I can understand the additional effort involved in keeping that up-to-date with minor refinements over time. Perhaps a hybrid of documentation and then links to shorter videos capturing individual steps.
Just my 2c....
