That is sort of the way I do things also :
# zpool status
pool: fibre0
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.

You noticed that the man page is not too clear on that eh?
zpool attach [-f] pool device new_device
Attaches new_device to an existing zpool device. The
existing device cannot be part of a raidz configuration.
If device is not currently part of a mirrored configura-
tion, device automatically transforms into a two-way
mirror of device and new_device. If device is part of a
two-way mirror, attaching new_device creates a three-way
mirror, and so on. In either case, new_device begins to
resilver immediately.
so yeah, you have it.
Want to go for bonus points? Try to read into that man page to figure out
how to add a hot spare *after* you are all mirrored up.
