Migrate Host Networking from vSphere Distributed Switch to vSphere Standard Switch

Before you can move the new vSAN cluster to the restored vCenter Server, you must first disconnect the hosts from the temporary vSphere Distributed Switch by using a temporary vSphere Standard Switch.

1. Disconnect a physical vmnic for each host from the vSphere Distributed Switch on the temporary vCenter Server.
   1. Log in to the temporary vCenter Server at https://<temporary_vcenter_server_fqdn>/ui by using the vSphere Client.
   2. In the Networking inventory, right-click the distributed switch and select Add and Manage Hosts.
   3. Select the Manage host networking task.
   4. On the Member hosts tab, select all hosts and click Next.
   5. On the Manage physical adapters page, select one vmnic, for example vmnic1, and then click Unassign adapter.
   6. In the Confirm Unassign Adapter dialog box, select Apply this operation to all other hosts and then click Unassign.
   7. Click Next.
   8. Click Next, Next and Finish.
2. Create a standard switch on each ESXi host.
   1. In the Hosts and clusters inventory, select the first ESXi host, and on the Configure tab, and select NetworkingVirtual switches.
   2. Click Add Standard Virtual Switch.
   3. Set the vSwitch Name to vSwitch0.
   4. Ensure the MTU is set to 9,000.
   5. Repeat this task to complete these steps for each ESXi host.
3. Connect ESXi hosts to vSphere Standard Switch.
   1. On the Virtual switches page for the host, click Add Networking.
   2. In the Add Networking wizard, select Physical Network Adapter and click Next.
   3. On the Select target device page, select vSwitch0 and click Next.
   4. On the Add physical network adapter page, select an unassigned physical adapter, for example vmnic1, from the adapter list, and move it under Active adapters, and click Next.
   5. Review the information on the Ready to complete page and click Finish.
4. Create a temporary management port group on the temporary vSphere standard switch.
   1. On the Virtual switches page for the host, expand vSWitch0 and click Add Networking.
   2. In the Add Networking wizard, select Virtual Machine Port Group for a Standard Switch and click Next.
   3. On the Select target device page, the standard switch will default to vSwitch0, click Next.
   4. On the Connection settings page, change the Network label to temp_mgmt, update the VLAN ID with the correct VLAN ID for the management VLAN, and click Next.
   5. Review the information on the Ready to complete page and then click Finish.
