you can enable autoexpand on the pool:
zpool set autoexpand=on tank
Insert a new disc, create partitions and replace disc by disc with:
zpool replace tank /dev/sdx /dev/sdy
After the disc is replace continue with the next disc.
With these steps you should be able to migrate to new discs without
If you have important data on disc, you should have a backup before you
