NSD Portability Conversion

Hitless Gateway Migration enables migration of Edges and Non SD-WAN Destinations (NSDs) from a Gateway to another Gateway with minimal to no network downtime.

During Gateway migration, if NSDs are associated with the Gateway, then the Enterprise user must perform NSD Conversion operation to configure portable NSD Virtual IPs to the Gateway by performing the following steps:
  1. Assign Portable Virtual IP to the Customer's NSD Configuration
    1. In the Enterprise portal, go to the customer's account view and navigate to Service Settings > Gateway Migration .
    2. Click the NSD Portability Conversion tab.
      Figure 1. NSD Portability Conversion
    3. Under the Portability Conversion Gateways section, locate the Source Gateway and click Start. The portability conversion process automatically fetches the Virtual POP IP from the Source Gateway and assigns it to the NSD.

    4. Copy the assigned Virtual POP IP from the Gateway Portable IP column and paste to the customer's NSD configuration.
    5. Confirm that this Virtual IP is assigned to the Customer's NSD configuration, and then select the The listed NSD sites have been configured checkbox.
    6. Click Next to perform NSD conversion.
  2. Perform NSD Conversion and Switch Gateways

    Apply configuration changes. Complete the conversion and switch tunnel parameters.

    1. In the Switch Gateways section, select the NSD from the list and click Convert NSD.

    2. Review the migration summary prompt in the dialog and confirm that the Customer-side NSD configuration is completed by selecting the The NSD has been configured checkbox.

      Note: If tunnel status verification fails, then the Undo Convert NSD button will be enabled.
      • Click Undo Convert NSD to revert back to the Public IP.
      • Click Retry Tunnel Verification to start verifying tunnel once again.
      • Click Skip Tunnel Verification to skip tunnel verification.

    After successful NSD portability conversion, the Gateway with NSDs associated is ready for Gateway Migration.
