R740xd - relocating HDD/SSD trays with RAID? (alien.top)

I currently have 10x SATA 2.5" SSDs RAID-6 on the front plane, caddy 0 to 9. However I would like to move this to 10~19. So, here are the questions.

I'm using H740P HW RAID.

Can I just power off and plug & put those SSDs?
Do I have to preserve the order? (like 0 => 10, 1 => 11, ... 9 => 19)

Of course, even if this works, I already have a backup and the storage ain't that important. It's just a ton of steam games and I don't want to re-download it.

Searched for Dell's manuals for R740 and R730, but couldn't find any of the "moving HDD/SSDs in a same machine"

Thanks in advance!

I can't say for certain in your case, but usually hardware RAID addresses disks by port, while software RAID addresses disks by serial.

So if it's a hardware raid I'd say it won't work - but I may be wrong, it's just from my experience with older raid controllers where you had to insert disks into their specific slot to not break the array.
