Question Upgrading Drives in a Storage Spaces Mirror

[fastoy]

I have a Windows 11 Pro system with a Storage Spaces two-way mirror. Unknown to me, it was "thin provisioned". It consists of 2 4TB drives giving "8TB" of capacity. I realize that this is really only 4TB of capacity.

I would like to upgrade this Storage Space to 2 8TB drives giving a true 8TB of capacity.

What steps would I need to do to accomplish this? When completed, can I remove the specification of thin provisioning so the true capacity is presented?

Unknown to me...

Sorry, but you really really need to undo this Storage Space thing, and institute a real backup situation.
What you have is not that.
