Another issue I have is--how to migrate my debian system from the old
original SSD to the new larger SSD?
As for macOS [1], it should be easy. There is a macOS application called
Time Machine that allows to backup macOS from the old SSD and to restore
it to the new SSD. This would work with a single boot system with macOS,
but I have no idea what will happen to Grub [2] in this process.
However my main concern is with the linux partition. How can I migrate
it? If I simply clone the linux partition from the old drive to the new
drive, I fear something would go wrong, as the new drive is different
and would require different drivers, missing in the original linux system.
What would be the best strategy?
[1] I have a dual boot system, and I have kept macOS mainly to keep the
possibility of firmware upgrades.
[2] Grub allows to boot debian. If I do nothing, Grub starts and boots
debian. If I press the "alt" key during startup, the Apple's original
EFI boot loader starts and boots macOS.
