I have a server consisting of a mirrored pair of UFS disks containing the OS, which is 7.0-CURRENT-200705, and a raidz zpool, with ZFS version 6. I want to upgrade the OS to 8.0-RELEASE, and upgrade the zpool. Since I don't have any important data on the OS disks, I plan to just do a fresh install of 8.0 on the UFS disk(s). My concern is how to do the upgrades without losing any zfs data. I believe I just need to do the following steps. Please advise if this will safely do the zpool upgrade, or whether a different sequence of actions is required to ensure I don't lose any ZFS data. 1. zpool export poolname 2. install FreeBSD 8.0 3. zpool import poolname 4. zpool upgrade poolname Is it really that easy? Thanks, Gary
