Replacing the motherboard or Raid controller in a Raid 0+1 set-up.

Tried to find information about this before posting a new thread but couldn't so here goes.

Running an ASUS A8N32-SLI Deluxe 939 NVIDIA nForce4 SLI X16 ATX AMD Motherboard. I have 4 identical drives set-up in Raid 0+1 on the NVIDIA nForce 4 SLI MCP chipset, not the Silicon Image chipset.

The motherboard died and I need to replace it. Do I need to find an identical raid controller or can the other raid controller detect my raid set-up and work with it?

I've had the system for about 4 years now so I'm not too disappointed that the mobo died. I'm hoping that I can take this opportunity to upgrade the cpu & ram.

If anyone knows any other threads that cover migrating from one raid controller to another I'd appreciate the pointer. Keep in mind, my PC is not working so I can't back-up the drives and re-build the array. Thanks in advance for any useful posts.
