Migrating Hosts

Before migrating the hosts, select a host migration plan.

For more information about what happens during host migration, see Changes Made During Host Migration in an End-to-End Migration.

If the Security Policies in your NSX-V environment use a partner service for Guest Introspection or Network Introspection or both, choose the host migration mode as shown in the following table.

Partner Service	Host Migration Mode
Only Guest Introspection	In-Place and Maintenance modes are supported.
Only Network Introspection	Maintenance mode is supported. However, Automated Maintenance mode is recommended. In-Place mode is not supported.
Both Guest Introspection and Network Introspection	Maintenance mode is supported. In-Place mode is not supported.

Important: Consult the VMware partner before migrating their service that is running on the NSX-V workloads. Check with the partner whether their service is supported for migration to NSX-T and seek their inputs before the migration. Partners will have their own guidance to migrate their services to NSX-T.

Caution: Host migration should be completed during the same maintenance window as Edge migration.

You must disable IPFIX and reboot the ESXi hosts before migrating them.

If the partner service in your NSX-V environment provides Guest Introspection or both Guest Introspection and Network Introspection service, follow the procedure in Migrate Hosts with Guest Introspection Service.

If the partner service in your NSX-V environment provides only Network Introspection service, follow the procedure in Migrate Hosts with Network Introspection Service.
