Migration of VMs between vCenter Server instances moves VMs to new networks. The migration process performs checks to verify that the source and destination networks are similar.

vCenter Server performs a number of network compatibility checks to prevent the following configuration problems:

  • MAC address compatibility on the destination host
  • vMotion from a distributed switch to a standard switch
  • vMotion between distributed switches of different versions
  • vMotion to an internal network, for example, a network without a physical NIC
  • vMotion to a distributed switch that is not working properly

vCenter Server does not perform checks for and notify you about the following problems:

  • If the source and destination distributed switches are not in the same broadcast domain, virtual machines lose network connectivity after migration.
  • If the source and destination distributed switches do not have the same services configured, virtual machines might lose network connectivity after migration.
