Hmm, I'm thinking no.  In order for the new controler to work it needs =
to
be setup. When new it has no config. You'd need to create a logical =
drive
stripe size, array size etc from the new controller bios point of view.=20
Make sure these settings are exactly the same setup as the old =
controller is using.
Usually creating a logical drive (RAID X) Is a destructive process.  I =
could be wrong. =20
Get a good backup first before changing controllers, then try it, and =
you'll have
Nothing but time to loose.
