rm -rf amd64 grub platformThe new contents of /mnt/eon0/boot should have amd64, grub, platform and the new x86.eon. Now, replace any custom changes you had in /mnt/eon0/boot/menu.lst. Also, do not run zpool or zfs upgrade until you're satisfied you like the new version as there is no way of going back to a previous zpool (currently v14) or zfs (currently v3) version. You can now reboot into the new EON ZFS NAS. From there you can re-run setup and updimg.sh to re-id your new version or mount your previous version and transfer any customizations.
