Hi
yes. but converting a node from 7-mode to Cdot involves a few tasks:
1. change boot vat to cdot, netboot a cdot image, disk and system reinitialization.
2. Obtain new set of licences for features in Cdot and a cluster licence. Per reply below - confirm you have a copy of the 8.2 licence keys.
3. Change the network connectivity to create the intercluster network between the nodes.
4. confirm hardware compatibility with the version you're going to (Disks, shelves, PCI cards and their location) at hwu.netapp,com
Speak with a NetApp or a partner to see if and how they can help with this. And to help with generating new set of licences (which I assume thy can only do for in-support systems).
