1. Configuring two appliances at HQ as the Grid Master. See Create the Grid Master bookmark657.
2. Logging in to the Grid Master and defining the members that you want to add to the Grid; that is, you configure Grid member settings on the Grid Master in anticipation of later joining those appliances to the Grid. See Define Members on the Grid Master bookmark658 bookmark658.
3. Logging in to the individual appliances and configuring them so that they can reach the Grid Master over the network and join the Grid. See Join Appliances to the Grid bookmark659.

After creating the Grid and adding members, you use the Data Import Wizard to import DHCP and DNS data from legacy servers. See Import DHCP Data and Import DNS Data bookmark660 and bookmark662.
Finally, you transition DHCP and DNS service from the legacy servers to the Infoblox Grid members. See Enable DHCP and Switch Service to the Grid bookmark667 bookmark667.

Using the Infoblox Data Import Wizard, import DNS data from the legacy hidden primary server at 10.0.1.5 to the new hidden primary server at 10.0.1.10 (the Grid Master). There are three phases to this task:

• Before Using the Wizardbookmark663:
  • Save the named.conf file from the legacy server to a file in a local directory on your management system.
  • Enable the legacy server to perform zone transfers to the NIOS appliance.
  • Configure three name server groups for the Grid, and allow the Grid Master/hidden primary DNS server at 10.0.1.10 to receive DDNS updates from the Grid members at 10.0.2.10, 10.1.1.10, and 10.3.1.10. These members act as secondary DNS servers and DHCP servers.
• Using the Wizardbookmark664: Define the source, destination, and type of DNS data in the DNS configuration file (named.conf) that you want to import.
• After Using the Wizardbookmark666: Check the imported DNS configuration file.
