Insights from 8.5 require additional configuration after upgrade
Valid from Pega Version 8.6
After you upgrade Pega Platform™ version 8.5 to 8.6, the Explore Data landing page might not include insights that come from the earlier version of the product.
What steps are required to update the application to be compatible with this change?
Run the pxUpgrade85Insights activity to make all insights from version 8.5 accessible for you in 8.6. By running this activity, you upgrade insights with new metadata that is required in version 8.6. For example, the pxUpgrade85Insights activity provides you with the option to set the visibility of insights to private, public or shared.
You can opt to use the the "alternate database" identified in the Reports Database field of the Data-Admin-DB-Table instance that supports the Applies To class of a report as the source for the report. This reduces the load on the database that serves your application when you run the report.
All Pega product release notes can be found on their product pages.
