Missing historical data after migration

Hi

I’ve been noticing, that after my update to Chirpstack V4, the historical data (such as received data, SNR, RSSI etc) is reset after the update. So if I updated the 18th of december, then data will show correctly from the 18th and forward, but there is no data before.

Is this a part of the migration script? Or do I need to manually find the data from v3 and move them to V4? (I really hope that it’s possible?) :slight_smile:
