Use vSphere vMotion

vSphere vMotion is a vSphere migration mechanism that moves a powered-on virtual machine from one ESXi host to another, with no service disruption or downtime. In this section we will describe how you can perform a vMotion migration using vSphere Web Client. Here are the steps:

1. (Optional) If your VM is powerd-off, power it on.

2. Right-click the VM you would like to migrate and select the Migrate option:

start vmotion

3. The Migrate Virtual Machine wizard opens. Select the Change host option as the migration type:

vmotion change host

4. Next, you need to select the ESXi host to which you want to migrate the virtual machine. Expand the inventory view and select the destination ESXi host:

vmotion compatibility check

Note that the compatibility check is performed. If you receive any error message, the migration will not continue. The warning messages will not prevent the migration.

5. Choose the vMotion priority. Mark the first option if you want the migration to receive a reserved share of CPU resources:

vmotion priority

6. Review the settings and click Finish to start the migration:

vmotion review

And that’s it. Your VM should now reside on a new host:
