I have a Dell Power Edge 2900 running MS SBS Small Business Server. It has 3 SAS 146GB HD in RAID 5 and 2 partition’s. I have made a backup using Acronis True Image Echo Server® (build 8,398). I want to replace these 3 drives with 3 SAS 300GB drive still with RAID 5. Would it be possible to add the 3 new drives as it's own RAID configuration and cloning the old drives to the new or should I remove the original 3 drives add and create a new RAID 5 using new drives then restore from an Acronis Image.
