I have over 30 years in the IT industry. During this time I have worked with a variety of products in a variety of industries.
When a VMware environment has both older and newer hardware, there is a setting in vCenter that needs to be set called EVC. This stands for Enhanced vMotion Compatibility. This allows the virtual machines to move seamlessly between host. However, you need to be able to determine what modes are compatible between the ones in each host. This tutorial will walk you through how to use the Broadcom Compatibility Guide to determine which modes are available between two different types of CPU.
NOTE: Before proceeding, to be successfully implemented all currently running virtual machines need to be on hardware compatibility version 14 or higher.

1. How To Determine Which EVC Modes Are Compatible Between Host.
2. Go to the following URL: https://compatibilityguide.broadcom.com.
3. Select CPU Series in the lower left panel.
4. Select the version of vSphere that is running in the environment.
5. Scroll down to CPU Series and select the types of CPU in the current cluster and the version in the host(s) to be added.
6. Scroll down and select the top box beside Enhanced vMotion Compatible Modes to select all options.
7. Now, scroll back up and select the View Matrix radio button.
8. Slide the bar under the output and look for modes where there are green checks for both processor types.
9. It is recommended to take the highest option available for future compatibility.

Installing used hardware in a home lab or other systems can have some challenges. Hopefully, the lesson learned here with a used NVMe drive will save someone else time and headache.
