Cisco Prime Network Registrar 8.3.3 Release Notes
 
Cisco Prime Network Registrar Bugs
The synchronization between version 8.3 and pre-8.3 local clusters must be done from an 8.3 regional cluster. Cisco 
Prime Network Registrar 8.3 protocol servers interoperate with versions 7.2 or later except as noted below.
Cisco Prime Network Registrar 8.2 and later DHCPv4 failover servers do not interoperate with versions prior to 8.2. 
Therefore, if you are upgrading from 8.1 and earlier to 8.2 and later, you must upgrade both failover partners. Also, 
any firewalls need to be updated to allow TCP traffic on the failover port (547). And, for 8.2 and later failover extends 
to DHCPv6.
The HA protocol version has been updated in Cisco Prime Network Registrar 8.0 and communications with earlier 
versions is not supported.
Caution:
By the nature of the EDNS0 protocol, Cisco Prime Network Registrar 8.3 DNS servers interoperate with earlier 
versions of Cisco Prime Network Registrar DNS (and third party DNS vendors). EDNS0 defines the interoperability 
with DNS servers that do not support EDNS0. Cisco Prime Network Registrar 8.3 DNS adheres to the RFC and 
consequently interoperates with earlier versions of Cisco Prime Network Registrar.
Cisco Prime Network Registrar 8.3 DDNSv6 interoperates with Cisco Network Registrar 7.0 and later DNS servers 
because of the use of the DHCID RRs (in place of TXT RRs for DDNSv6).
Cisco Prime Network Registrar 8.3 does not interoperate with Cisco Prime Network Registrar IPAM 8.1.1 or 8.1.2. 
An updated version of Cisco Prime Network Registrar IPAM is required to interoperate with Cisco Prime Network 
Registrar 8.3.
