Question Regarding RAID with 890FX Upgrade

So I am helping a friend of mine upgrade her system, and her current system board is a M4A89TD PRO which of course uses AMD's 890FX chipset, the SB850 south bridge, and JMicron's JMB361 as the storage controller.  (Link to list of specifications posted below.)

https://www.asus.com/Motherboards/M4A89TD_PRO/specifications/

As part of a system upgrade she was considering getting a new Asrock motherboard, more specifically the 990FX Killer.  However, she currently has a couple of SSD's in a RAID 0 and was hoping to avoid wiping them as part of this process.  In an attempt to help her I have been trying to research if the newer SB950 (and whatever storage controller it uses) is backwards compatible with arrays setup on a system using SB850 hardware, but unfortunately have not been able to come up with an answer. 

So with that in mind: does anyone here happen to know if upgrading motherboards will necessitate a complete wipe of her system?

Thanks for taking the time to reply.  However, just so we are clear the SB950 and SB850 use compatible storage methods so it should automatically detect her RAID array if she gets the new motherboard?  I have pretty much always used a dedicated controller, but I know with those sometimes you run into issues so I just wanted to make sure before I made a purchase.  Sorry if it seems like I am being overly cautious or anything.

Back the array up prior if it holds mission critical data. That doesn't need repeated.

If you are certain that the array is running on the SB850, chances are good that you can migrate it to the SB950. The chip itself is basicly the same, a so called rebrand. But firmware differences may cause you trouble. On the other side, most mainboard manufacturers don't care about AMD's AHCI/RAID firmware when updating their BIOS, so most of them use one from 2009 or 2010 (inappropriate for SSDs by the way).
