ZFS and switching from ad to ada disks.

[Arthur Chance]

I'm currently running 8.1-R without AHCI enabled, with a raidz zpool 
based on /dev/ad* disks, plus one system disk that's UFS2, mounted using 
partition labels. I need to enable AHCI in order to get hot pluggable 
eSata capability, and that's going to rename the disks to /dev/ada*. 
Will zfs handle that OK, or should I zpool export before the switch and 
zpool import after?
