This host appears to be an ioBroker SLAVE system. Migration will be skipped. Is this correct? [Y/n]: y
Explicit migration from file to jsonl is not necessary, skipping...

No Database migration was done.
If this was done on your master host please execute "iobroker setup first" to newly initialize all objects.

updating conf/iobroker.json
