Before upgrading a product in your vRealize Suite environment, you can pre-validate the product upgrade request to identify issues that can possibly cause an upgrade failure.
Pre-validation is an optional step that ensures a smooth product upgrade using vRealize Suite Lifecycle Manager. To pre-validate as part of the upgrade process, you can set the preValidate toggle in the PATCH /action/upgrade/product request. See Patch Product Upgrade Request Then Upgrade.
Pre-validation is particularly useful when upgrading from an older version of a product or in a production environment where a clean upgrade is critical. However, a best practice is to pre-validate every product upgrade request.
