After migration has finished, some additional actions might be required.

  • If you migrated from NSX for vSphere 6.4.4, perform a reboot of all hosts that have migrated to NSX-T. The reboot must be done before you upgrade to a later version of NSX-T.

  • During migration, all transport nodes are added to a group called NSGroup with TransportNode for CPU Mem Threshold. This group ensures that the transport nodes have the correct CPU memory threshold settings in NSX-T. This group is required after migration has completed. If you need to remove a transport node from NSX-T after migration, you must first remove the transport node from this group.

    Make sure you are in Manager mode and then select Inventory > Groups to remove the transport node from the NSGroup with TransportNode for CPU Mem Threshold group. For more information about Manager mode, see Overview of the NSX Manager in the NSX-T Data Center Administration Guide.

  • Verify that you have a valid backup and restore configuration. See "Backing Up and Restoring the NSX Manager" in the NSX-T Data Center Administration Guide.
