Many vRealize Operations Manager metrics are discontinued or changed for the 6.7 release. The changes apply primarily to capacity planning, badges, widgets, and raw metrics. Some vCenter adapter and vSAN adapter metrics were also discontinued. The changes update the capacity analytics and improve product scale. VMware has made many of these changes transparent or nearly so. Still, multiple changes can impact management packs that you might be using, plus dashboards and reports that you have created. Before upgrading, run the vROps Pre-upgrade Readiness Assessment Tool (Assessment Tool) that helps you understand the precise impact on your environment through a detailed report.
Why Run the Assessment Tool
Various changes in vRealize Operations Manager can impact the user experience. When you run the Assessment Tool, you get an HTML-formatted report identifying all the points in your system affected by the changes. Further, the Assessment Tool gives recommendations for the correct changes to be made in your content for the 6.7 release.
You must run the Assessment Tool on the instance of the vRealize Operations Manager installation that you want to assess - typically your production system. The Assessment Tool does not alter anything in your system, and deletes itself when it has completed its run. It leaves behind only the assessment result - a support bundle that you download from the Support Bundles section of the vRealize Operations Manager Administration user interface.
For detailed instructions on running the Assessment Tool, see Running the vRealize Operations Manager 6.7 Pre-Upgrade Readiness Assessment Tool.
