Explains how to migrate a tenant from a multitenant Cisco Catalyst SD-WAN deployment to a single-tenant deployment.
Prerequisites to migrate a tenant from a multitenant SD-WAN overlay to single-tenant SD-WAN deployment
Ensure these prerequisites are met for a successful migration.
-
Manually migrate the serial number of the WAN edge device associated to a virtual account on the source Cisco SD-WAN Manager overlay in Cisco PNP to the destination virtual account.
-
Ensure that you manually create the controller profile on the destination virtual account for on-prem to on-prem or cloud to on-prem deployments.
-
Ensure that the source and destination Cisco SD-WAN Manager instances use the same Certificate Authority (CA) and software release; a mismatch can block tenant data import and cause migration failure.
-
Ensure that you check the CPU, memory, and disk size requirements of the destination overlay Cisco SD-WAN Controller before the migration to meet the WAN edge forecast requirements.
-
Ensure that there is no overlap between the configured system IP addresses of edge devices and the destination overlay controllers.
-
Ensure that all devices in a tenant have connectivity to the Cisco SD-WAN Validator in the destination single-tenant overlay. The migration procedure supports a Cisco SD-WAN Validator on the single-tenant deployment configured either with IP or DNS.
Push any required static route configuration to the devices before initiating any of the migration steps.
-
Ensure that there are valid control connections from Cisco SD-WAN Manager to the WAN edge devices in the source overlay.
Configuration
-
Ensure that the destination single-tenant Cisco SD-WAN Manager does not have any configurations before migration. You can configure only mandatory admin settings and all other configurations can be done after data import.
-
Configure a maintenance window for the multitenant overlay before performing this procedure. Refer to the information about configuring a maintenance window in the basic settings section of the Cisco Catalyst SD-WAN Control Components and Device Management Guide.
-
Ensure that the WAN edge devices that are configured using CLI, device template, or configuration groups, have an IP host mapping to the Cisco SD-WAN Validator in the destination single-tenant overlay.
-
We recommend that you use a custom script or a third-party application like Postman to execute the API calls.
Migrate a tenant from a multitenant SD-WAN overlay to single-tenant SD-WAN deployment
Use these steps to migrate a tenant from a multitenant SD-WAN overlay to single-tenant SD-WAN deployment.
Procedure
| 1. | Export the multitenant deployment configuration and statistical data from a Cisco SD-WAN Manager instance controlling the source overlay.
|
|||||||||||||
| 2. | Check the status of the data export task in SD-WAN Manager When the task is successfully complete, download the data from the following URL: |
|||||||||||||
| 3. | Import the data to the single-tenant instance, as follows: |
|||||||||||||
| 4. | After the import, update information related to the device templates, policies, and other deployment-specific parameters.
|
|||||||||||||
| 5. | If a centralized policy is present on the source tenant, the migration copies the policy to the destination overlay. We recommend creating Cisco SD-WAN Controller templates and attaching them to the devices. Apply the centralized policy to devices in the destination overlay before proceeding. |
|||||||||||||
| 6. | Obtain the migration token using the token URL from the previous step.
|
|||||||||||||
| 7. | On the multitenant SD-WAN Manager instance, initiate the migration of the overlay to the single-tenant deployment.
|
When the task succeeds, WAN edge devices form control connections to controllers in the single-tenant deployment; the WAN edge devices are no longer connected to the controllers of the multitenant overlay.
What to do next
In SD-WAN Manager, check the status of the migration task.
After the migration is successfully complete, perform the following tasks:
-
If WAN edge devices have SD-WAN Manager signed certificates in the source setup, the certificates are cleared from the device during migration and control connections are lost. Recertify the devices in the destination.
-
The passwords are updated to the default password in the destination overlay for users created on a tenant in the source overlay. Make any configuration changes specific to the destination overlay.
-
Delete the tenant on the source overlay after migration and verification is complete.
