An organization upgrades a SharePoint 2010 environment to SharePoint 2013. A site collection is running in SharePoint 2010 compatibility mode.
You must verify that the following features will function correctly when the site collection is upgraded to SharePoint 2013 native mode:
✑ List views
✑ Custom web parts
✑ Content query web parts
✑ Subsites
You need to ensure that you can perform verification testing without impacting the current user experience.
