Hello,
I am currently working with an HA (High Availability) pair of two Infoblox NIOS DDI appliances that support DHCP services, which I need to migrate. The new appliances are also Infoblox NIOS DDI (two appliances in an HA pair). As I’m relatively new to Infoblox products, I have a few questions about the migration process and would appreciate your assistance:
- Configuration Replication:
- To replicate the configuration from the existing appliances to the new ones, is it sufficient to export the current configuration and import it into the new appliances without any modifications, even though there are differences in the NIOS versions between the two sets of appliances? If modifications are required, does Infoblox provide any tools or resources to assist with this task?
- Lease Database Transfer:
- Is there a lease transfer feature in Infoblox NIOS DDI products that I can use to migrate the lease database from the existing appliances to the new ones, ensuring a seamless transition for the DHCP clients? If such a feature is not available, what method does Infoblox recommend for replicating the lease database during a migration?
- Interface State During Migration:
- During the migration, the old appliances will be isolated from the network and replaced with the new ones, but they will not be powered off (only the network interfaces will be down). I would like to know if the state of the interfaces could impact the DHCP service and the lease database. Specifically, does the NIOS appliance retain the contents of the lease database even when the service interface is down? Additionally, does the DHCP daemon remain active even when the interface is down? This information is crucial as I am relying on it in case a rollback is necessary.
Thank you for your support.
