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.
|
||
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.
|
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.
|
||
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:
In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reconfigure the Appliance Using the Configuration Wizard" 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.
|
||
Step 6 |
Cisco DNA Center automatically pushes telemetry updates and required system certificates to your network's devices.
|
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.
|
||
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:
In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Reconfigure the Appliance Using the Configuration Wizard" 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.
|
||
Step 7 |
Cisco DNA Center automatically pushes telemetry updates and required system certificates to your network's devices.
|
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). The new appliance will use the same IP addresses that were configured for the previous appliance's interfaces.
Procedure
Step 1 |
(Optional) Upgrade to the latest Cisco DNA Center release. See the Cisco DNA Center Upgrade Guide.
|
||
Step 2 |
Decommission the appliance you are replacing. |
||
Step 3 |
Set up the new appliance at your data center, ensuring that you install the same Cisco DNA Center release that was installed on the previous appliance. Also make sure that you set the same IP address for that was configured previously for the Enterprise interface. In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Configure the Primary Node Using the Maglev Wizard" topic. |
||
Step 4 |
Restore the backup file that was created on the previous appliance. In the Cisco DNA Center Administrator Guide, see the "Restore Data from Backups" topic. |
||
Step 5 |
Reestablish connectivity with Cisco ISE. In the Cisco DNA Center Administrator Guide, see the "Configure Authentication and Policy Servers" topic.
|
||

If self-signed certificates were in place on your network's devices, reprovision them in order to update their Cisco DNA Center certificates. In the Cisco DNA Center User Guide, see the "Update Device Configuration Using Telemetry" topic.
|
Scenario 5: Replace a Standalone Cisco DNA Center Appliance with an Appliance with More Cores (Different 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). The new appliance's interfaces will use different IP addresses than the ones that were used on the appliance that's being replaced.
Procedure

|
||
Step 2 |
Decommission the appliance you are replacing. |
