You want to install a new clustered Data ONTAP 8.3 system with a FA8080. The customer has unused licenses available from a clustered Data ONTAP 8.1
system.
What should be considered in this scenario?

A.
You can use your licenses from the clustered Data ONTAP 8.1 system for the new clustered Data ONTAP system.

B.
You must call NetApp Support for evaluation license keys.

C.
You can use your license from the clustered Data ONTAP 8.1 system for about 90 days.

D.
In clustered Data ONTAP 8.2 and later, use node-specific license keys that will only install on the controller for which they were purchased.

Explanation:
Any clean installation of Data ONTAP requires version-appropriate license keys for the Data ONTAP version and mode being deployed. Current policies require a
valid support case to provide new license keys for Data ONTAP versions other than the version originally purchased.
