Upgrading a 2x500GB SSD bootable RAID 1 array to 2x1TB SSD RAID 1 array with Acronis
I am looking to upgrade my Dell Precision 3431 RAID 1 array that is using the built-in Intel motherboard RAID which is currently configured as 2x500GB SSD drives to bigger 2X1TB SSD drives. This computer does boot into Windows 10 from this array. These are the only drives in the system other than a DVD player. How can I accomplish this?
Can I simply:
1) Use Acronis (from boot disc) and perform a System Image from the current RAID 1 array to a USB backup drive.
2) Shutdown and remove the 2x500GB SSD drives and install the 2x1TB SSD drives.
3) From BIOS, create a new RAID 1 array with the same name as the old array.
4) Boot again from ATI boot disc and restore the image from the USB backup drive to the new RAID 1 array.
Any help is appreciated!

@Steve Smith as usual is giving excellent advise. In addition, rather than just removing the disks and putting in the new disks, I would delete the raid array and then, after replacing the drives, create a new array. While it is possible that the new array to be created automatically, I have never tried. I have swapped 3 drives in a RAID 5 array onto a different PC and it automatically recognised the array from information on the individual drives. This why I would delete the array before removing the "old" drives to assure that the raid signature is removed from the disks.
