Swap RAID controllers

Hi,

I have a hardware RAID controller in a server and I strongly suspect it's faulty and causing the server to become un-responsive. I'd like to swap the controller to see if the problems goes away. I suspect that means I will loose the disk configuration. I don't expect a definite answer but does anyone know if I can simply swap the card (same manufacture, possibly different model) and it pick up the disk configuration?

Fingers crossed,
Dermot.
