I currently have a PR2100 in RAID1 configuration.
I could do with some more capacity soon and would like to upgrade to a PR4100, but switching to RAID5 (with 3 discs at first and then 4 disks).
Is there an recomended method to achieve this?
I imagine I could take one of the RAID 1 disks to use a starting point, Then copy the data from that, within the PR4100 to 3-other-disks configured as RAID5.
Could I then re-add the source disk as part of the RAID5 set?
