Using the Pre-Upgrade Readiness Assessment Tool for VMware Aria Operations 8.16 and 8.16.1


Article ID: 324331


Updated On:




This tool provides you with an impact analysis following the reduction of metrics in various versions of the product as well as with the validation check results of the system's upgrade ability. 

If you are currently leveraging any of the discontinued or disabled metrics in your existing content such as reports, alerts, dashboards etc., the VMware Aria Operations (formerly known as vRealize Operations) Pre-Upgrade Readiness Assessment Tool can help you scan your content for these metrics and provide you recommended replacements in form of a pre-upgrade assessment report web page. This web page provides you all the recommended replacements for the content (such as Metrics, Properties, Dashboards, Alerts etc.) which have been discontinued / disabled with VMware Aria Operations 8.16.  You can use these recommendations to make appropriate changes to the content post upgrade to VMware Aria Operations 8.16 or 8.16.1.

Note: Only vRealize Operations 8.10 and later can directly upgrade to VMware Aria Operations 8.16 or 8.16.1.  For two step upgrades download Pre-Upgrade Assessment Tool from the download page of corresponding version.

For other versions of vRealize operations, see vRealize Operations Pre-Upgrade Readiness Assessment Tools (67311).
