We are a running a Solaris 10 production server being used for backup

I would like to know if it is viable to add larger disks to zfs pool to
grow the pool size and then remove the smaller disks?
This is covered in the documentation:

I would assume this would degrade the pool and require it to resilver?
A resilver is required without it there is no way to get your data on to
the new drives.
Wither the pool is degraded or not depends on wither you dettach an
existing side of a two way mirror to do the replacement with the larger
drive or if you create a three way mirror first and then dettach one of
the size of the original two way mirror.
