This will work beautifully, assuming you suffer no failures. Don't forget
to zpool labelclear the p1 drives after you remove them from p0. It is very
critical to warn you that any failure on p0 will result in data loss. Once
you destroy p0, any failure in p1 will result in data loss, until the
resync is complete. Be sure you back up any data you can't afford to lose
to a third location.
