If you need to replace an existing host NIOS-X server with a new one (due to malfunctioning or misconfiguration on the old hostNIOS-X server), you can use the "replace" function to do so. You can replace NIOS-X virtual and physical hostsservers. The “replace” function supports zero-touch provisioning through the Cloud Services Infoblox Portal.

To ensure that all the services moved from the old host NIOS-X server operate properly on the new hostNIOS-X server, you must select a new host server that can support all the services currently running on the old hostexisting server. Otherwise, certain services might not function properly on the new hostNIOS-X server. For example, if you replace an old host existing NIOS-X server running the Data Connector service with a new host NIOS-X server that does not support the Data Connector service, the service will not be operational on the new hostserver. |
To replace an existing hostNIOS-X server, you first set up the new host NIOS-X server and connect it to the Cloud Services Infoblox Portal through zero-touch provisioning. Ensure that the new host NIOS-X server is in the Active Online state and that there are no active services enabled on the new hostserver. The replace function will automatically remove the services and configuration from the old host server and move them to the new host server without the need for manual configuration. The old host will be in the Pending state and thereafter goes to the Awaiting Approval state. Only after the host goes to the Awaiting Approval state, you can select the host and approve it from Host -> Approve. To replace a host
The following table lists the respective states of the NIOS-X servers before, during, and after the replace operation.
| Replace Operation | Old Server State | New Server State |
|---|---|---|
| Before operation | Online (with services running): This state is applicable only to NIOS-X servers that are already online. Offline: This state is applicable to offline NIOS-X servers, such as misconfigured or corrupted NIOS-X servers. | Online (without services running) |
| During operation | Pending > Awaiting Approval | Offline |
| After operation | Awaiting Approval Note: The NIOS-X server stays in the Awaiting Approval state and no action is required. | Online (with services running) |
