Preparing Layer-2 Bridging for Lift-and-Shift Migration

A lift-and-shift migration may require a layer-2 bridge for overlay logical switches.

A layer-2 bridge is required if overlay is used in the environment and you want to minimize downtime. A layer-2 bridge is not required if VLAN is used in the environment. A layer-2 bridge is also not required if you plan to migrate all the workload VMs in a single maintenance window and you can accept downtime during the migration.

Note: NSX 4.x does not support vSphere 6.7 and you cannot deploy an Edge node on an vSphere 6.7 host. If your NSX-V environment is running vSphere 6.7, you must upgrade vSphere or migrate using a previous version of NSX that supports vSphere 6.7.

If a bridge is required, perform the following tasks.
