Timeshift, again.
Timeshift snapshots just the space consumed by the installed distro. You can set it to include a Home folder or a Home partition.
It has zero compression, that is, 1:1 - but it reports size in GB, not GiB, so if your source install consumes 10 GiB, the snapshot may be, say, 11 GB.
On the target machine, reformat it to EXT, and if all computers are UEFI, create an ESP (EFI System Partition) of, say 500MiB as FAT32, and an EXT4 partition that is whatever size you like,but bigger than the snapshot.
Using an SSD as storage for the snapshots, the restore process will work very quickly with a USB 3 cable to a USB 3 port.
After you press Restore within Timeshift, you simply give it the new details of the devices for the ESP partition and the EXT4 partition, and tell it to proceed.
Timeshift will make the necessary adjustments to /etc/fstab at the receiving end.
This will work faster than Clonezilla, dd, RedoRescue and Foxclone, as I believe Bob has found recently.
In mid-June 2022, after my wife passed away, I used this method using my WD My Book 4 TB SATA drive (which had all my snapshots stored), and moved maybe 80 distros from my computer in te garage to the computer in the study.
