Replacing Servers

If you need to replace an existing NIOS-X server with a new one (due to malfunctioning or misconfiguration on the old NIOS-X server), you can use the "replace" function to do so. You can replace NIOS-X virtual and physical servers. The “replace” function supports zero-touch provisioning through the Infoblox Portal.
Note
To ensure that all the services moved from the old NIOS-X server operate properly on the new NIOS-X server, you must select a new server that can support all the services currently running on the existing server. Otherwise, certain services might not function properly on the new NIOS-X server. For example, if you replace an existing NIOS-X server running the Data Connector service with a new NIOS-X server that does not support the Data Connector service, the service will not be operational on the new server.
To replace an existing NIOS-X server, you first set up the new NIOS-X server and connect it to the Infoblox Portal through zero-touch provisioning. Ensure that the new NIOS-X server is in the Online state and that there are no active services enabled on the new server. The replace function will automatically remove the services and configuration from the old server and move them to the new server without the need for manual configuration.
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) |
To replace a server, complete the following:
- From the Infoblox Portal, click Configure > Servers.
- Select the the server you want to replace.
- Click ... next to the server > Replace.
In the replace server widget, select the new server from the Replacement Server list, and then click Save & Close.
A confirmation message is displayed. Click Confirm to replace the existing server with the new server, or click Cancel to cancel the operation.
Note
- Once you confirm the operation, the old NIOS-X server goes into the Pending state and thereafter goes into the Awaiting Approval state.
- It might take a few seconds for the replace operation to complete and all the services on the new server to go online.
- All the configurations on the new server will be overwritten by the services and configuration moved from the existing server.
