Understand these points about Catalyst Center and IPv4/IPv6 addressing:

• Catalyst Center does not support dual stack addressing, which is the simultaneous use of both IPv4 and IPv6 addressing.

• To switch from one addressing scheme to the other, you must Reimage the appliance.

• You cannot restore a backup file from an appliance that uses IPv4 to an appliance that uses IPv6, or vice versa.

• If your appliance uses IPv6 addressing, see the "IPv6 Limitations" section in the Release Notes for Cisco Catalyst Center for a description of the features that are not supported.
