Before you upgrade the layers of the SDDC, verify that your system meets the general system requirements for this operation.

  • Review the Release Notes for each VMware product in the SDDC.

  • Review the VMware Validated Design Planning and Preparation documentation and the individual prerequisites for the upgrade of each VMware Validated Design layer to understand the hardware and software requirements that might impact the SDDC upgrade.

  • Verify that the server hardware has been certified with vSphere 6.5 Update 1. For information, see the VMware Compatibility Guide.

  • Ensure that the server hardware meets the updated memory requirements of the SDDC. See ESXi Host Physical Design Specifications in the VMware Validated Design Architecture and Design documentation.

  • Review any custom integration that might have occurred outside of VMware Validated Design to ensure compatibility with the new versions of VMware products within the SDDC.

  • Review any third-party products that might be used in your environment to ensure compatibility with the new versions of VMware products within the SDDC.
