I have a 2011 Mac with a ARC-1800x PCIe Raid controller hooked up to a miniSAS SanDigital tower with a 12TB RAID6 array; I am upgrading to a new Mac Pro, with only thunderbolt ports. I have a OWC Helios 2 to support the PCIe card and want to use the old array in the new computer. When I put the old card in the new computer will it simply read the array no problem? Or will I have to recreate the whole array from scratch? I have about 10TB of data on the array and I would like to avoid the time of creating an additional copy if necessary.
