Swapping hub to new hub (Hubitat)

Because of another issue, I may need to replace my primaryC8 with a new C8. I anticipate doing this with the cloud migration tool. What will I need to-do to make the transition as easy as possiblein regards to my dashboards and Sharptools?

I would make sure to read through the Hubitat Migration Help Article:

If you are migrating between Hubitat hubs, you should be able to use the SharpTools Hubitat Migration Tool noted in the above linked article to migrate things accordingly.
