How to clone a SSD with Fedora 43 on a Btrfs Partition

How do I clone a SSD with Fedora 43 on a Brtfs partition to a SSD in an external case. I have tried using

dd if=/dev/nvme0n1 of=/dev/sda bs=1M

however, despite dd completing successfully, the Brtfs partition is shown as ‘unknown’ on the external device. The other partitions (Efi, boot) are cloned properly.

This used to work with Fedora on an Ext4 partition. Now after installing Fedora 43 on Brtfs, this doesn’t seem to work.

I used to have an exact copy of my system on an identical HD/SSD, in case of a failure, I would simply swap the drive. I’m trying to accomplish the same thing now, however it doesn’t seem to work with Brtfs.
