I'm not very sure what are you talking about (I never had a problem during the ZFSv6 -> ZFSv13 transistion when I had ZFS as root), maybe I have overlooked something? What was the problem you had when going from ZFSv6 to ZFSv13? The change between ZFSv13 and ZFSv14 (actually, this commit only adds ZFSv14 support which is necessary for importing OpenSolaris 2009.06 zpools, we are still a few revisions behind) is quite minimal one and have almost no impact to our codebase at this moment. Importing older zpool won't change anything on it (say, if it was v6, it's still v6, etc), and I personally didn't have any manual interaction on my desktop (the only difference is that it's using UFS as / and boot and mount ZFS in a sparse manner). What I would do is to build and install a kernel that supports ZFSv14, see how it's going, then upgrade the zpool at a later time when I have full backup, for zfs as root the 'zpool upgrade' may have some problem IIRC (the reason why I don't use ZFS as root FS anymore is because I couldn't rollback root ZFS to a previously taken snapshot, and once the ZFS gets screwed up one have to boot from a rescue disc) but others should be just fine.
