When you upgrade the components that support the management cluster in the SDDC , you upgrade the Compute vCenter Server in Region A and repeat this operation in Region B.

About this task

Compared with from the earlier version of this design, upgrading the VMware Validated Design vSphere layer for the shared edge and compute cluster has been simplified to a single-step operation. In this version, you upgrade the Compute vCenter Server in Region A. Then, you repeating this operation in Region B.

VMware Validated Design 4.1 introduces a new convention for host and object names in the SDDC. The step-by-step upgrade guidance uses the new names for both the pre- and post-upgrade SDDC setups. For information about the new convention, see Mapping Component Names Between Versions 4.0 and 4.1 of VMware Validated Design.


  • Download the vCenter Server Appliance VMware-vCenter-Server-Appliance-6.5.0.x-build_number-patch-FP.is file.

  • Verify that vSphere DRS on the shared edge and compute cluster is set to Fully Automated for the duration of the upgrade operations to have management workloads automatically migrated from hosts while they are being upgraded.

  • Verify that all compute ESXi hosts have the lockdown mode disabled for the duration of the upgrade.

  • Ensure that any integration with the Compute vCenter Server instances in the environment has been quiesced of all activities, including but not limited to, users requesting new virtual machines with or without virtual wires by using the vRealize Automation Cloud Management Platform (CMP), third-party integration that might automate the ordering or deployment of new virtual machines, and administrators manually creating new virtual objects. Without quiescing the environment, rollback operations could be disrupted by orphaned objects that are generated after you have taken snapshots. You might also have to extend the time of the maintenance windows.

  • Verify that a backup of the Compute vCenter Server instances exists. See the VMware Validated Design Backup and Restore documentation.

What to do next

  • Verify that vCenter Server are operational after the upgrade. See Validate Platform Services Controller and vCenter Server Instances in the VMware Validated Design Operational Verification documentation.
