Migration from vsphere Standard switch VSS to distributed switch VDS

Migration of standard switches to distributed Switches
1. Management Network + Virtual Machine
Both physical NICs perform "Traffic Management" and "vmotion ",
1. Manage hosts --> migrate a physical Nic to a distributed switch.
Do not migrate vmnic and vmk together, because the link to vmk is lost after the vmnic is migrated to VDs.
2. Manage hosts --> migrate all 'vmkernel management Network' and VMS of the switch network to the distributed switch.
3. migrate another physical Nic to a distributed switch. We recommend that you delete the NIC and add the NIC to the VDS to avoid uplink Port location issues.
4. Ping the corresponding port and VMS during each migration to test their redundancy.

2. Storage Network migration
1. Manage hosts --> migrate two physical NICs to a distributed switch at the same time, and select IP-san as the target port group. Migrate the vmkernel at the same time.
2. Remove from the standard switch

Unbind two physical NICs for redundancy
1. delete a physical Nic and add the NIC to the specified location on the physical adapter of the VDS (depending on the port binding policy of the VLAN ).
2. Manage hosts --> migrate the iSCSI ports of two vmkernel to the VLAN of the specified IP-SAN of the distributed switch.
3. Delete the remaining physical NICs and add them to VDs.
4. Maintain Ping test connectivity.
