G-Speed Studio R - Merging Disk Arrays

Hello - I’ve erroneously set up two separate physical drives in my G-Speed Studio R as two disk arrays, and would like to merge the two into one. I have data in one of them and the other is completely new - is there a way to do this safely so I don’t lose any data?

Thank you!

Extract the data elsewhere then delete your RAID and create a new one that includes all the drives then transfer the data back from the other location.
