Set up with out formatting hard drives

Does anyone know if this device can be configured WITHOUT  formatting the hard drives, going through the set-up routine it ask no tell me it need to format my hard drives, my hard drives contain data that I would rather not lose, I was hoping to up grade from my old usb drive bays to this but I can’t lose my data. Any suggestions would be greatly appreciated.

Unfortunately, the RAID array needs to be created, configured, and managed by your WD My Cloud EX2. As such it requires clean hard drives and asks you to format them if it detects partition data. I’d recommend copying the files to a different location.
