How to Migrate Tenant Replicas From a Standard Switch (vSS) to a Distributed Switch (vDS)

7. Apply the configuration settings.
   For each tenant using this hardware plan, the new vDS networks will appear on the host.

Part 2: Reconfigure Tenant Replicas on SP-Side

8. Update each tenant replica that will be migrated to change the network adapter manually to the vDS VLAN.
   There are two ways to accomplish this:
   • In vSphere Web Client, right-click on the old VLAN and select the option: Migrate VMs to Another Net…
     
     or
   • In vSphere Web Client, edit the Network adapter settings for each VM. 
   Note: When the network configuration is changed, two networks will appear in the VM configuration because existing snapshots still use the old network configuration. When these snapshots are removed according to the retention policy, only the new network will be shown for the VM.

Part 3: Update Tenant(s) Replication Jobs

9. Coordinate with Tenants to have them remap networks for their replication jobs.
   There are two ways they can accomplish this:
   • Change replication jobs settings: 
     1. Edit replication job.
     2. On the Name step, enable the select option: Network remapping
        
     3. On the Network step, Add a network mapping to switch jobs to the new network.
     
     or
   • In the tenant's Veeam Backup & Replication Console, under the Backup Infrastructure > Service Providers section, right-click on the service provider entry and select the option "Manage default gateways" to remap Windows VMs.
