I have several times successfully upgraded mirrored volumes with new
disks without any downtime at all. Just change one disk, let the mirror
rebuild, change the other disk, wait for rebuild again, tell the logical
drive to present all the new space and then extend the filesystem. No
downtime.
Just an additional hint: Before you start doing this procedure, in order
to minimize risk you may want to do a verification/repair run over the
original mirror (if your controller supports this) to make sure that
both disks are in sync and there are no defective sectors on the disk
you are subsequently copying the data from. Otherwise there could be
some rude awakening ...

Uwe
