Good day!

I have a TS-453Be with one 10tb hard drive. This hard drive is almost full, so I bought two, 24tb hard drives and I am currently setting them up for Raid 1. Once the raid is built I'd like to completely transfer the data from my 10tb drive to the Raid 1 and then remove the 10tb drive from my system. What is the best way to go about this?

Thank you!
