Is there a way to do a key export before doing an upgrade?

Last upgrade wiped out manually entered keys and had to reenter them.

box has import option so why not an export option.

if you really want it, you can do it by yourself.
Use HelloMenu tool export block ac from old software, and import bock ac to new version.

older models had in USB upgrade an option to choose what to upgrade.

this left the channel or keys in tact while doing a software upgrade.

Is there an option to do dump and restore the keys from the dump file?

the import for a softcam.key file is there but not to save/export the keys before an update.
