Perform the tasks in the following sections to prepare the NSX environment. What to read next Deploy an NSX Manager ApplianceYou must deploy a new NSX Manager appliance to run the migration coordinator. Do not deploy an NSX Global Manager. Add a Compute ManagerBefore you can start the migration process, you must add the vCenter Server that is associated with NSX-V as a compute manager in NSX. Change the Global MTU SettingWhen an Edge Services Gateway (ESG) is migrated, the MTU setting of the interfaces is not migrated. A default value of 1500 is used. You can change the default value using the API. Create an IP Pool for Edge Tunnel End PointsIf your NSX-V environment uses Edge Services Gateways, you must create an IP pool in the NSX environment for the Edge Tunnel End Points (TEP) before you start the migration. Plan the Mapping of the NSX-V Topology to the NSX TopologyReview the NSX-V topology and decide how to map it to the NSX topology. During the migration, the "Define a Topology" step will prompt you for the mapping. Deploy NSX Edge NodesYou must deploy NSX Edge nodes as a virtual machine on ESXi using an OVA or OVF file. Join NSX Edge Node VM with the Management PlaneYou must join the NSX Edge node VM you created to the management plane. Configure NSXfor a User-Defined Topology MigrationBefore migrating a user-defined topology, you must configure NSX. Register Third-Party Guest Introspection Service with NSXIf Security Policies in your NSX-V environment use third-party Guest Introspection service provided by a partner, register the partner service with NSX before you start the migration. Register Third-Party Network Introspection Services with NSXIf Security Policies in your NSX-V environment use third-party Network Introspection services provided by partners, partner services must be registered with NSX before you start the migration.
