+You should stop this service before to proceed the copy, else there is a risk your mysql database to be corrupted.

 Now, your SATA drive contains a complete copy of your system, but one important thing is missing: your kernel is in ''/tmp/sata/boot'', but this folder should actually mount /dev/mmcblk0p1, which already contains the system you are currently running.

 Can you log into your cube ? Congratulations ! It worked !
-====== Cleaning ======
+====== Cleaning up ======

+Now, your old system is cluttering the ''/boot'' folder. To clean it up, you can remove everything in this folder, and reuse the ''/boot.old'' copy we did earlier.
 <code>
 cd /boot
 rm -rf * # /!\ proceed carefully /!\
-update-initramfs -u
+mv /boot.old/* .
+rmdir /boot.old
 </code>
-Check if ''/boot'' got repopulated by the last command. If so, you are good to go.
+Everything should be fine now !
+An alternative approach: remove everything from ''/boot'', then run ''update-initramfs -u''. This will regenerate everything necessary inside ''/boot''.
