If the OS is on the RAID1 (mirror) do you have to re-install the OS when upgrading to RAID5?

Unless your RAID controller is capable of "transforming" from RAIDx to RAIDz, you will have to count on deleting your current logical disk, destroying your current RAID set (of 2 disks), creating a new RAID set (of 5 disks for example), creating a new logical disk spanning those 5 disks, and creating a new partition.
In short, your data will be gone and you'll have to re-install.
