| We would like to create a new structure, copy the data there but we want a downtime of the system as short as possible. The system should also be prepared for beadm.

| + | For this we need a new pool and then copy the data using ZFS features. | ||
| + | |||
| + | Get partitions of old pool: | ||
| + | <code console> | ||
| + | gpart show ada0 | ||

| + | gpart create -s gpt ada1 | ||
| + | gpart add -a 4k -s 128M -t efi ada1 | ||
| + | gpart add -a 4k -s 256K -t freebsd-boot -l boot1 ada1 | ||
| + | gpart add -a 4k -t freebsd-zfs -l disc1 ada1 | ||
| + | </ | ||

| + | Then we create the new pool but we do not mount it: | ||
| + | <code console> | ||
| + | zpool create newzroot gpt/disc1 | ||
| + | zpool export newzroot | ||
