Updating an xHA pair that has software earlier than version 6.1.0 - BlueCat Integrity - 9.3.0

DNS/DHCP Servers using software predating version 6.1.0 don't support the use of the eth1 interface for xHA data replication.

1. From Address Manager, update the servers in the xHA pair to software version 8.1.0 or greater.
   Note: Address Manager v9.3.0 supports xHA on DNS/DHCP Servers running software version 9.0.0 or greater only.

   • For more information, refer to Updating or applying patches to servers in an xHA pair.
2. On each DNS/DHCP Server appliance, log in to the DNS/DHCP Server Administration Console and configure the eth1 network port. For more information on configuring the eth1 port on DNS/DHCP Server, refer to Configuring the xHA Backbone Connection from the Adminstration Console.
3. Connect a network cable between the eth1 ports on each DNS/DHCP Server appliance in the xHA pair. To locate the eth1 ports on your DNS/DHCP Server appliances, refer to the installation posters that came with your appliances.
4. From the Address Manager user interface, edit the xHA pair. Under xHA Communication Interface, select the Enable xHA backbone communication check box and set the IPv4 addresses and netmasks for xHA/eth1 interface of the Active and Passive nodes.
