Before the migration, verify that your environment meets the following requirements.
- NSX-V versions 6.4.4, 6.4.5, 6.4.6, 6.4.8 and later are supported for all migration modes with the following exceptions:
- VMware Integrated OpenStack migration supports NSX-V 6.4.11 and later.
- Cross-vCenter to NSX Federation migration supports NSX-V 6.4.11 and later.
- See the VMware Product Interoperability Matrices for required versions of vCenter Server and ESXi.
- The version of ESXi used in your NSX-V environment must be supported by NSX-T.
- vSphere Distributed Switch versions 6.5.0, 6.6.0, and 7.0 are supported.
- The NSX-V environment must match the NSX-T system requirements for ESXi, vCenter Server, and vSphere Distributed Switch.
- DNS must be functioning in the NSX-V environment.
- If you are migrating VMs that are DHCP servers, you must configure a Segment Security profile appropriately on NSX-T. For more information, see "Create a Segment Security Segment Profile" in the NSX-T Data Center Administration Guide.
- If your Edge Service Gateways have their MTU setting changed, you must change the global MTU setting in NSX-T. See Change the Global MTU Setting.
- NSX-V does not support running another transport node inside it running VXLAN on the same transport VLAN. If you have an NSX-T Data Center Edge on an NSX-V host, the NSX-T Data Center Edge VTEP VLAN must be different.
