Migrating VMs to another network hangs on "Loading..." at the step "Select VMs to Migrate"

Products

• VMware vCenter Server

Issue/Introduction

During the migration wizard in vCenter when migrating VMs to another network, the process hangs on "Select VMs to migrate".

Environment

vCenter 7.0

Cause

This is a known issue which is caused by VMs connected to a DVS which have an empty port group value.

Resolution

This will be resolved in a future release of vCenter.

Additional Information

To work around this issue, check the DVS port list:

1. Select the DVS -> Ports
2. Look for ports with a VM listed under the "Connectee" column which have no value in the "Port Group" column.
3. Reassign the VM to a different port group (Right click on the VM -> Edit Settings)
