Clone / Replicate Entire Database?

I have an existing InfluxDB with 6 months of precious data. I’ll call this ‘dc1’. I’d like to move this data to a new server, ‘dc2’, without losing any historical data, data in transit, or data of the moment. I’ve successfully tested telegraf’s clustering ability, which allows me to write data from this point forward simultaneously to dc1 and dc2 --but what about the historical data? Backup/restore seems like a problematic and messy option. Thank you for any suggestions!
