Not if you don't upgrade the pool it won't. ZFS can import and work with an old version of the filesystem fine. The manual page for zpool upgrade says: "Older versions can continue to be used" Just import it on Solaris 5/08 without doing the upgrade. Your ZFS pool will be available and can be served out from the new version. If you do find any problems (which I wouldn't expect to be honest), you can plug your old snv_70b boot disk in if necessary. > zfs send of the /zvol/ufs volume would take 2 days.

I don't think you need to do this though, I really think your idea of swapping the boot disks is the best way of getting this server up & running. The absolute worst case scenario is that Solaris 5/08 also crashes on the old Thumper which means you have faulty hardware. If that happens you'll probably need to move your data drives to the new chassis and hope it's not a bad drive causing the fault. Either way, let me know how you get on.
