1. Connect vSphere or VMware Infrastructure Client to your vCenter Server.
2. Click on the ESX host.
3. Click the Configuration tab.
4. Click Advanced Settings under Software.
5. Select Migrate and change Migrate.Enabled to 0.
6. Click OK and close.
7. Click on Advanced Settings.
8. Select Migrate and change Migrate.Enabled to 1.
9. Click OK and then Close.

Note: If you see the invalid parametererror after resetting Migrate.Enabled to 1, see Performing a vMotion or adding a network card to a virtual machine fails with the error: Necessary module isn't loaded. (2013128)

If these steps do not resolve the issue, try increasing the timeout for migration network operations after Step 4 and then continue with the remaining steps. Also, ensure to repeat these steps on the destination host.

1. Click the Configuration tab.
2. Click Advanced Settings under Software > Migrate.
3. Change Migrate.NetTimeout to 60 seconds. The default is 20 seconds.
4. Click OK and then Close.
