How to migrate VM from one PVE cluster to another

[thijz]

Hi,

does your token have permissions to access the storage?

EDIT: also, there should be upgrades available, 7.4-18 is not the latest PVE 7 version.

The source cluster is our production cluster (50+ hosts) so it's not that easy to upgrade to the latest 7.4 i'm afraid

errr ... token does not have the correct permissions :-/
fixed that (added full access for the token) and tried again, but fails with a different error :
