I just had a look at my Hub Protect subscription and noticed that its all messed up.
Under MyAccount->Subscription it show that no hub are registered, but under MyAccount->Subscription it shows I have a hub protect Subscription that expires next February. I just purchase a C8 pro for an update from my C7 and hope this wont mess up my migration.,
It shouldn't but if for any reason, it does, please be sure to submit a subscription case, and we will un-mess it up: Subscriptions – Hubitat Support
Just received my C8 Pro and migration DOES NOT work. It will only let me register the hub under my old email address, and it show no cloud backups at all. It's probably been at least 6 months ago since I requested a change in email address, and now it looks like the changed only works for some things, as my old email address is still alive on your system,
Back in the early summer when support helped you transfer your hub to the new account, they explained that subscriptions can't be transferred from one account to another. It doesn't look like you responded to the last email, though, so maybe you didn't see it.
Your current account doesn't have any subscriptions to be transferred, since the subscription was canceled on your old account. Your old hub has non-transferable active service until February.
So what do i need to do to you to migrate this new hub to my C7 data.
If you registered both with same account, then C7 backup should be available to your new hub.
I tried to register my existing (old) hub by clicking subscriptions and it doesn't let me select my old hub
Did you try simply reloading (browser-button reload) that web page?
For as long as I can remember, every time I access it, it always gives me that same "Failed to load hub data" message, but a page reload always gets past that.
If you de-registered the old hub, you lost the active service and the backups you have created under the new account. You should be able to register the hub with new account and if you register the new hub with the same account, then the new hub should see the old hub's backups.
This will be resolved with the updates we've been working on, along with one of your long time feature requests. Not telling you which one, because you asked for it many months ago. 
Blockquote You should be able to register the hub with new account and if you register the new hub with the same account, then the new hub should see the old hub's backups.
I did this registering the new hub with my existing login/password. When I click on setting->Hub Migration it cant find any cloud backups at all. I need to migrate my C7 data, and without that capability I have no use for this C8-Pro hub. If I need to purchase another cloud backup to make this work then I'm ready to do this.
You do not need a subscription to migrate from older hub:
Be sure to check out this document: How to Migrate to a New Hub | Hubitat Documentation
I can create cloud backup with my C7 with no limitation and create several yesterday and this morning. After disconnecting old C7 and with my C8P log into my existing account no backups show up.
Is it because this shows up in my subscriptions:
Which hub is the above screenshot for?
That's really great news -- all these various improvements will obviously be a nice win for all subscription holders, but also welcome relief for you (no longer having to run manual interventions in all these cases, or at least a heckuva lot less)!
My old C7 hub
Could this be the problem. Says none register (C7 hub) but I can save cloud backups.
