2012 R2 Storage Spaces - Split a mirrored virtual disk and keep data

Hi

I have a storage pool containing 2x physical disks. I have created a mirrored virtual disk on top of those physical disks, occupying all the space.

I would like to split this pool/mirror back into 2 separate disks, but retain the data. So basically end up with 2 separate disks each containing a copy of the data.

Is this possible?

Thanks
