That it, 7.0.5 is the current GD release and there are quite a few fixes between 7.0.2 and 7.0.5, so I'd update the ontap version first. You can go to the NOW site and download, then save the pacacke in the etc/software directory.
Ensure the package is in the right place with the software list command, then sofware install packagename and a reboot to install the package.
