Prerequisites

Before you complete any of data migration procedures described in this document, back up your appliance’s Automation and Assurance data. For scenarios that require users to have the current and new clusters running at the same time during the migration process, we recommend that you provide a unique backup path for each cluster.

Scenario 1: Move a Standalone Cisco DNA Center Appliance Between Data Centers (Same IP Addresses)

In this scenario, you are moving a Cisco DNA Center appliance from one data center to another, keeping the same IP addresses that are already configured for the appliance's interfaces.

Procedure

Step 1

(Optional) Upgrade to the latest Cisco DNA Center release. See the Cisco DNA Center Upgrade Guide.

Note

 

If you upgrade, we recommend that you back up the data on your appliance. In the Cisco DNA Center Administrator Guide, see the "Back Up Data Now" topic.

Step 2

Power off the appliance, then move it to the new data center.

Step 3

Power on the appliance.

Step 4

Ensure that connectivity between Cisco DNA Center and the devices it manages is established.

Note

 

For deployments running non-Cisco ISE AAA servers, use the System Health tool to confirm that Cisco DNA Center can reach these servers and connectivity is established.

Scenario 2: Move a Standalone Cisco DNA Center Appliance Between Data Centers (Different IP Addresses)

In this scenario, you are moving a Cisco DNA Center appliance from one data center to another one, using different IP addresses than the ones that are currently configured for the appliance's interfaces.

Procedure

Step 1

(Optional) Upgrade to the latest Cisco DNA Center release. See the Cisco DNA Center Upgrade Guide.

Note

 

If you upgrade, we recommend that you back up the data on your appliance. In the Cisco DNA Center Administrator Guide, see the "Back Up Data Now" topic.

Step 2

Power off the appliance, then move it to the new data center.

Step 3

Power on the appliance, then use the Configuration wizard to specify:

  • The IP addresses that you want to assign to the appliance's Enterprise, Management, and Internet interfaces.

  • The virtual IP addresses that you want to assign to the Enterprise and Management interfaces.

In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reconfigure the Appliance Using the Configuration Wizard" topic.

Note

 

If you want to change the appliance's intracluster IP address, you must first reimage the appliance, installing the Cisco DNA Center release that was present when the latest backup file was created. In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reimage the Appliance" topic.

Step 4

After you complete the Configuration wizard, log in to the Cisco DNA Center GUI.

Step 5

Reestablish the pxGrid connection between Cisco DNA Center and Cisco ISE (which was severed when you updated the Enterprise interface's IP and virtual IP addresses in the previous step). In the Cisco DNA Center Administrator Guide, see the "Configure Authentication and Policy Servers" topic.

Note

 

For deployments running non-Cisco ISE AAA servers, use the System Health tool to confirm that Cisco DNA Center can reach these servers and connectivity is established.

Step 6

Cisco DNA Center automatically pushes telemetry updates and required system certificates to your network's devices.

Note

 

Because you are using the same appliance (with its data intact), you don't need to restore its latest backup file.

Scenario 3: Move a Standalone Cisco DNA Center Appliance Between Data Centers (Different IP Addresses, Same FQDN)

In this scenario, you are moving a standalone Cisco DNA Center appliance from one data center to another one. The appliance will use different IP addresses than the ones that are currently configured for its interfaces. It will also continue to use its current FQDN.

Procedure

Step 1

(Optional) Upgrade to the latest Cisco DNA Center release. See the Cisco DNA Center Upgrade Guide.

Note

 

If you upgrade, we recommend that you back up the data on your appliance. In the Cisco DNA Center Administrator Guide, see the "Back Up Data Now" topic.

Step 2

Step 3

Power on the appliance, then use the Configuration wizard to specify:

  • The IP addresses that you want to assign to the appliance's Enterprise, Management, and Internet interfaces.

  • The virtual IP addresses that you want to assign to the Enterprise and Management interfaces.

In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reconfigure the Appliance Using the Configuration Wizard" topic.

Note

 

If you want to change the appliance's intracluster IP address, you must first reimage the appliance, installing the Cisco DNA Center release that was present when the latest backup file was created. In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reimage the Appliance" topic.

Step 4

You'll use the same hostname and domain name for the appliance, but you must update your DNS server with the IP address that's used for lookup entries.

Step 5

After you complete the Configuration wizard, log in to the Cisco DNA Center GUI.

Step 6

Reestablish the pxGrid connection between Cisco DNA Center and Cisco ISE (which was severed when you updated the Enterprise interface's IP and virtual IP addresses in the previous step). In the Cisco DNA Center Administrator Guide, see the "Configure Authentication and Policy Servers" topic.

Note

 

For deployments running non-Cisco ISE AAA servers, use the System Health tool to confirm that Cisco DNA Center can reach these servers and connectivity is established.

Step 7

Cisco DNA Center automatically pushes telemetry updates and required system certificates to your network's devices.

Note

 

  • Because you are using the same appliance (with its data intact), you don't need to restore its latest backup file.

  • Because the FQDN is unchanged, PnP and other use cases that use FQDN should work without any issues.

Scenario 4: Replace a Standalone Cisco DNA Center Appliance with an Appliance with More Cores (Same IP Addresses)

In this scenario, you are replacing a standalone Cisco DNA Center appliance with another appliance that has more cores (for example, replacing a 56-core appliance with a 112-core appliance).
