During the host migration step in an end-to-end migration, changes are made to migrate NSX-V hosts to NSX-T hosts.

  • NSX-V software is uninstalled.
  • NSX-T software is installed.
  • For vSphere Distributed Switch versions 6.5.0 and 6.6.0:
    Hosts are configured with N-VDS to replace vSphere Distributed Switches:
    • Each N-VDS is created with a name that references the distributed switch name. For example, distributed switch ComputeSwitchA is created as N-VDS nvds.ComputeSwitchA.
    • If different clusters use different distributed switches to back logical switches, an N-VDS is created with a name that combines all the distributed switch names. For example, if ComputeCluster1 and ComputeCluster2 use distributed switch ComputeSwitchA to back logical switches and ComputeCluster3 uses ComputeSwitchB to back logical switches, the N-VDS is created as nvds.ComputeSwitchA.ComputeSwitchB.
    • PNICs and vmks in the vSphere Distributed Switch are migrated to N-VDS.
    • NSX-V VTEPs are migrated to NSX-T TEPs.
  • For vSphere Distributed Switches version 7.0:
    Hosts configured for vSphere Distributed Switch version 7.0 continue using the same switch after migration.
    • PNICs and vmks in the vSphere Distributed Switch remain connected on the same vSphere Distributed Portgroups.
    • NSX-V VTEPs are migrated to NSX-T TEPs and connected to standalone ports on the same vSphere Distributed Switch.

Note: If NSX-V has multiple VTEPs and a single LAG configuration, after migration the LAG will have a single TEP and in failover mode.
