Hello ThangaPandiyan,

I am not aware of an option to convert a RAID 0 to a RAID 1 without data loss.

I would recommend to follow the below steps to transfer the data from the RAID 0 to the RAID 1.

Create image of current RAID0
Remove old disks
Install new disks
Recreate array as RAID1
Restore the information from image

Kind regards,

Wouter

As long as you have a functional cache module, additional drives can be added to the array and then migrate the raid level. This can be done via the GUI or CLI using ACU/SSA

my standard disclaimer when working with live data is to have a valid backup in case something goes wrong in the process.
