Unraid drive config

Hello all! I had a quick question. I recently just got unraid to try for 30 days. I had bought a dell r710. It has the perc 6/i controller. This does not support Jbod mode. So for just testing and messing around with unraid. I have ordered a H200 card that can be flashed to IT mode for Jbod. I wanted to know if i the drives attached to the perc “1 drive in raid 0” can just be passed through with all the original data. or if they will need to be reformatted and than mounted. Thanks.
