Manually adding devices in database.db?

[Tul47]

Hi,
Trying to migrate from ezsp to znp adapter, I'm struggling to avoid a full re-pair of everything.
Is it possible to delete database.db and coordinator_backup.json to regenerate from 0, then manually add devices in these (and configuration.yaml) to avoid re-pairing?
My first attempt got all my devices back in zigbee2mqtt, but they didn't work - They have no network routes.

Any way to do this would be much appreciated.
