The Data Center Expert OVA is created using ESXi 4.0. It supports version 4.1 and can run on versions up to 7.x but may have decreased capabilities on versions above 4.x.
You can upgrade the VM compatibility with later versions in the VMware UI, particularly to increase the number of CPUs extended to a DCE VM.
When DCE is deployed to a ESXi 7.0 host, CPUs are limited to 8. After upgrading the VM compatibility, you can increase the CPUs based on the capabilities of the ESXi host.
Power off the VM in vSphere.
Right click the VM and select Compatibility > Upgrade VM Compatibility.
A warning is displayed about reverse compatibility that advises you to make a backup. When you are ready, click YES.
Select the compatibility version for the VM upgrade. Choose the version that matches your ESXi environment. Click OK.
Your VM is now compatibility with the ESXi version you selected, and you can increase the number of CPUs extended to your DCE VM.
