zpool query

Hi,

I'd like to convert a zpool made of two striped disks and make it so that they are a mirror.

Aside from removing the data from that zpool, destroying it, then making a mirror in the usual way, is there a way of doing this in-place without having to move the data off?

The zpool isn't root-on-zfs, it's just data. This is on 13-stable, so openzfs.

thanks in advance
