Migration tool is not working

I get following error while upgrading from v3 to v4

Try it with Chirpstack v4 running and v3 AS and NS not running

The status of chirpstack-application-server and chirpstack-network-server were stopped and Chirpstack v4 and chirpstack-gateway-bridge were running state.

The cause is probably that the record exists in one database, but not in the other (e.g. it exists in the NS DB, but not the AS DB). Maybe this should be logged as an error instead of a panic? I made it as a panic as I wanted it to fail in case of data-inconsistency.
