Hi,

Metadata restore is meant to be done at the same version of XCP-ng, because otherwise the database/structure is different. You will NEVER upgrade this way.

The right way to upgrade is to use the ISO, it will also make a backup of your 8.2 in case you have an issue, so you can restore it.

@olivierlambert thanks, just to be sure.
