I have to wipe the disks and want to set up the system von scratch on after that. But of course I don't want to miss the licenses, so the question is how to back them up and restore them after the wipe.
The old method with the command "license" don't show the keys, only the installed licenses:
First: Thanks for your reply. And now of course a "but":
Deleting volumes is not the same as wiping a disk. Due to data security reasons these disks has to be wiped with DoD standard and certificate - there are personal relevant data on them and so this has to be done.
I know that the licences are bound to the serial number of the machine and so they can't e transferred, but a transfer is not what should be done. We only want to reinstall them on the same machine. And I think that should be possible. At the very end the system disks could get a problem also and that shouldn't be a reason to buy all licenses again...
