We had a machine that was using a Intel DQ965GF Motherboard that failed, so we have now switched to an Intel DQ35J0 motherboard.

Our Problem is that the old board was using RAID 5 using the Intel Matrix controller which I belive was based upon the ICH8DO series chipset the new motherboard uses the ICH9DO chipset.

We would like to know if it possible that the new controller can except the drive as is, we like to keep the data intact.

The raid system is in a 3 drive RAID 5 configuration.

Hope this makes sence.

You will likely not be able to keep the data intact if you just configure the raid on the new controller. I have found that when migrating disks in an array you need to move them to a board with the EXACT same controller. Unfortunately, even then sometimes it doesnt work. A new controller is almost definitely going to want to configure the drives in a new array, wiping the data from the drives in the process.

Yes you can. This is one awesome feature of Intel's ICHxR chipsets. You can go from 8 to 9 to 10. You just can't go backwards.
