1.) Debian 12 is the latest stable version of debian. Install it, then run the curl script to install umbrel. Debian is minimal, widely used, and well supported by software.
2.) If you already have block data, you can transfer it to the new node and reindex without downloading again.

P.S. if your machine has spare resources, you could install Proxmox on it and run your node in a VM. https://nullcount.com/how-to-install-umbrel-in-a-proxmox-virtual-machine/
When your node is virtualized in a type 1 hypervisor like proxmox, it greatly expands the kinds of high availability and redundancy techniques you can implement.
For example, I migrated my LN node from one machine, to another server running proxmox and the whole migration was done while the node was routing payments. Not a second of downtime during the migration to new hardware.
The VM sounds like a good option. Being able to back and restore the whole VM would really help with redundancy.

This is the way: vm. I'm using vmware workstation though on a ubuntu desktop host to run my node (just switsching from citadel to start9). If you change config, just take a snapshot and delete it if all works well. And you backup the vm to an external drive.
Another benefit: You can have small offline (not connected to the internet) encrypted VMs with sparrow or electrum, export the xpub for a watch only wallet. I don't use hardware wallets ...

Its amazing! Game changer. Can also easily spin up other nodes to try out without messing with your live node.
Just be careful working with LN data. The LN penalty mechanism will "steal" your sats if you restore an LN node from an expired channel state.

For Justice Transactions they only apply to individual channel correct, not the whole node?
Example: Node with 100 Channel crashes and die, node operator has a backup from yesterday. Since yesterday only one forward/transaction has occurred on one channel
Node operator restores from yesterday backup.
The 1 channel is only available for justice transaction?

Correct.
