If you do export to 751, and then import into hAP ac lite – no problems. And if you make a binary backup that, of course, will!

Only, you will need to configure your Wi-Fi 5GHz, as in 751 it is not.

No problems, only Wi-Fi on the new set up.
Also backup before update the version and then also before you restore, update hAp AC to the same version, for example between 6.36 and 6.37 there is no compatibility.
I don't really know how things are with the binary compatibility of backups but better version of still not to be confused.
(PS I bekapy configs in a text format for storage in the Gita, export file=backup)
