Hi Dick (from the solaris on x86 list), - First off, and you may already know this, you can upgrade - but it's a one-way ticket. You can't change your mind and go "backwards", as in, down-grade to a previous release. And, what if you want to restore a snapshot to a box running an older release of ZFS... - Secondly, you're not *required* to upgrade. If there is even a 1 in a 1,000,000 chance that you might want to use the pool with a previous release of *olaris - *don't* do it! And this includes moving the pool over to a different *olaris release - which is a requirement that cannot always be foreseen. - 3rd, in many cases, there is no "loss of features" by not upgrading. Again - I say - in most cases - not in all cases. To examine the current version or to upgrade it, please read (latest version of) the ZFS admin guide doc # 817-2271. Look at "zpool get version poolName" and "zpool upgrade" Recommendation (based on personal experience) leave the ondisk format at the "SXDE" default version for now.
