Techniques are very similar, except you copy files with rsync and restore a file system with partclone, then make the required alterations. Partclone may be easier if you don’t want to manually setup your btrfs config, just be aware of possible duplicate UUIDs.
Process looks more complicated than it actually is, most of the work is manual partitioning, encryption and bootloader config.
