Discover Existing Site-to-Site VPN Tunnels from On-Prem Management Center

When you onboard the on-prem management center to CDO, the existing site-to-site VPN policies on the threat defense devices will be imported into CDO If the site-to-site VPN policies are created for an on-prem management center that has already been onboarded, you must click Check for Changes to import the policies. After importing, these policies can be managed through CDO and deployed manually from the on-prem management center.
