How to install 1.1.1 on Proxmox

My 0.5.4 install on top of Ubuntu in a Proxmox VM, I have a 2TB SSD mounted for the Umbrel installation. The Bitcoin Node is currently using 785gb to store the blockchain. It begs the question I can’t seem to find any answer to, is how will a small data mount point hold the block chain?

The migration procedure has you back up to an external USB drive, and I question if that include the huge blockchain.

Do I need to blow off my 2tb ssd and need to resync the chain? Because it seems that way to me.

Any suggestions would be appreciated.
