If you have multiple boot environments, make sure that you don't upgrade zfs beyond the highest version supported by all boot environments. (e.g, when using liveupgrade and such) But beyond that, it's better to upgrade; typically, whenever I upgrade to a newer Solaris version, I upgrade BEFORE booting in the new boot environment. (So I'm sure that both still support the zfs version) Casper _______________________________________________ opensolaris-discuss mailing list [email protected]
