Cisco DNA Center Second-Generation Appliance Data Migration Guide

Data Migration Overview

This document describes how to migrate data to either an individual Cisco DNA Center second-generation appliance or a three-node cluster of second-generation appliances. Cisco DNA Center supports the following migration scenarios:

  • Migrating data to second-generation appliances that use the same interface IP addresses that are configured on first-generation appliances.

  • Migrating data to second-generation appliances that use interface IP addresses that are different from the ones that are configured on first-generation appliances.

  • Forming a cluster that consists of one first-generation appliance and two second-generation appliances.


Note

The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on standards documentation, or language that is used by a referenced third-party product.

Prerequisites

Before you complete the data migration procedure described in this document, have the following information available:

  • The IP addresses that are configured for the interfaces on your first-generation appliance. This is applicable only if you plan to configure the same addresses on your second-generation appliance.

  • A list of the Cisco DNA Center packages that are installed on your first-generation appliance and their version number. To get this information, do one of the following:

    • Log in to the appliance and run the maglev package status command.

    • For Cisco DNA Center 1.3.3.0 or earlier, choose > About > Show Packages.

    • For Cisco DNA Center 2.1.2 or later, click the Help icon () and choose About > Packages.

  • The configuration information for your backup server.

Migrate Data to Second-Generation Appliances

Complete the following procedure to migrate data to an individual Cisco DNA Center second-generation appliance or a three-node cluster of second-generation appliances.

Procedure


Step 1

On your first-generation appliance, do the following:

  1. Back up the appliance’s Automation and Assurance data.

    In the Cisco DNA Center Administrator Guide, see the "Back Up Data Now" topic.

  2. Disconnect the appliance from your network.

Step 2

On your second-generation appliance, do the following:

  1. Configure the IP addresses that you want to use for your appliance’s interfaces.

    You can use the same IP addresses that are configured on your first-generation appliance or specify different IP addresses.

    In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the topic that is specific to the configuration wizard you want to use and your appliance type:

    • If you are configuring a second-generation appliance using the Maglev Configuration wizard, see the "Configure the Primary Node Using the Maglev Wizard" topic.

    • If you are configuring a 44- or 56-core second-generation appliance using the browser-based configuration wizard, see the "Configure the Primary Node Using the Expert Configuration Wizard" topic in the "Configure the 44/56-Core Appliance Using the Browser-Based Wizard" chapter.

    • If you are configuring a 112-core second-generation appliance using the browser-based configuration wizard, see the "Configure the Primary Node Using the Expert Configuration Wizard" topic in the "Configure the 112-Core Appliance Using the Browser-Based Wizard" chapter.

    Important 

    When reconfiguring your access switches to match the high-throughput settings on your Cisco DNA Center appliances, be aware of the following differences between first-generation and second-generation appliances:

    • Unlike first-generation appliances, where the configured VLAN must be set up on a switch port and match what is configured on the appliance's Cisco UCS Virtual Interface Card (VIC) 1227, second-generation appliances only support native VLANs.

    • First-generation appliances only support the trunk switchport mode, while second-generation appliances only support the access switchport mode.

  2. Install the same versions of the Cisco DNA Center packages that are installed on your first-generation appliance.

    In the Cisco DNA Center Administrator Guide, see the "Download and Install Packages and Updates" topic.

  3. Restore the data that you backed up in Step 1.

    In the Cisco DNA Center Administrator Guide, see the "Restore Data from Backups" topic.

  4. Integrate Cisco ISE with Cisco DNA Center.

    In the Cisco DNA Center Second-Generation Appliance Installation Guide, see the "Integrate Cisco ISE with Cisco DNA Center" topic.

Step 3

Ensure that Cisco ISE is integrated properly with Cisco DNA Center and that your wireless LAN controller is operational.

  • If you are migrating data to only one second-generation appliance, stop here.

  • If you are setting up a three-node cluster, proceed to Step 4.

Step 4

Configure the second and third appliances in your Cisco DNA Center cluster.

See the following topics in the Cisco DNA Center Second-Generation Appliance Installation Guide:

  • If you are configuring a second-generation appliance using the Maglev Configuration wizard, see the "Configure a Secondary Node Using the Maglev Wizard" topic.

  • If you are configuring a 44- or 56-core second-generation appliance using the browser-based configuration wizard, see the "Configure a Secondary Node Using the Expert Configuration Wizard" topic in the "Configure the 44/56-Core Appliance Using the Browser-Based Wizard" chapter.

  • If you are configuring a 112-core second-generation appliance using the browser-based configuration wizard, see the "Configure a Secondary Node Using the Expert Configuration Wizard" topic in the "Configure the 112-Core Appliance Using the Browser-Based Wizard" chapter.
