Explains how to migrate a single-tenant Cisco Catalyst SD-WAN overlay to a multitenant deployment.
Prerequisites to migrate single-tenant SD-WAN overlay to multitenant SD-WAN deployment
Follow these prerequistes to ensure a successful migration.
-
Ensure that the edge devices in the single-tenant deployment can reach the SD-WAN Validator in the multitenant deployment
-
Ensure that the template, routing, and policy configuration on the edge devices is synchronized with the current configuration on SD-WAN Manager.
-
Configure a maintenance window for the single-tenant overlay before performing this procedure. Refer to the information about configuring an SD-WAN Manager server maintenance window in the Cisco Catalyst SD-WAN Control Components and Device Management Guide.
-
We recommend that you use a custom script or a third-party application like Postman to execute the API calls.
-
The software versions of the SD-WAN Controllers and WAN edge devices must be identical in both the single-tenant and multitenant deployments.

Migrate single-tenant SD-WAN overlay to multitenant SD-WAN deployment
Migration of a single-tenant overlay to a multitenant deployment is only supported with the SD-WAN Controllers deployed on-premises. Migration is yet to be supported with cloud-hosted SD-WAN Controllers.
Procedure
| 1. | Export the single-tenant deployment and configuration data from a SD-WAN Controller instance controlling the overlay. While exporting the data, SD-WAN Controller attempts to detach any CLI templates from the edge devices in preparation for the migration to the multitenant deployment. If prompted by SD-WAN Manager, detach CLI templates from the edge devices and execute the export API call again.

| 2. | Check the status of the data export task in SD-WAN Manager. When the task succeeds, download the data using the URL |
|||||||||||||
| 3. | Import the data exported from the single-tenant overlay, on a multitenant SD-WAN Manager instance. When the task succeeds, on the multitenant Cisco SD-WAN Manager, you can view the devices, templates, and policies imported from the single-tenant overlay.

| 4. | Obtain the migration token using the token URL obtained in response to the API call in step 3.
|
|||||||||||||
| 5. | On the single-tenant SD-WAN Manager instance, initiate the migration of the overlay to the multitenant deployment.
|
If the task succeeds, WAN edge devices form control connections to controllers in the multitenant deployment; the WAN edge devices are no longer connected to the controllers of the single-tenant overlay.
What to do next
In SD-WAN Manager, check the status of the migration task.
Attach any CLI templates detached from the edge devices (in Step 1) after migration to the multitenant deployment. Before you attach the templates, update the Cisco SD-WAN Validator IP address and the Organization name to match the configuration of the multitenant deployment.
In the single-tenant deployment, if Cisco SD-WAN Manager-signed certificates are installed on cloud-based WAN edge devices, the certificates are cleared when the devices are migrated to the multitenant deployment.
You must re-certify the devices on the multitenant SD-WAN Manager. If enterprise certificates are installed on the cloud-based WAN edge devices, the certificates are not affected by the migration.
