For clarification purposes, very Hubitat Elevation comes with a backup option to a local storage. If you can save a local backup from the hub that is giving you troubles, you can restore that backup to the new hub. Loading a local backup doesn't require a subscription and it restores apps, drivers, settings and custom code. The only thing that it doesn't do is restoring Z-Wave Network, so devices will need to be repaired. Also any cloud connected service will need to be reauthorized.
Hub Protect is very useful when catastrophic events happen. We strongly recommend adding Hub Protect plan to your new hub. Not only does it extend the warranty of your hub for the life of the plan, should the new hub fail (thus saving you money that you would spend on a new hub), but also you will have a cloud backup that allows you to load onto the new hub, so you don't have to rebuild your Z-Wave network, as well as automations.
