I am migrating SharePoint 2013 web application to SharePoint 2016 using content database backup/restore approach. I am seeing below error message for all "Excel Web Access" webpart instances in SharePoint 2016. As per my analysis, this web part is depricated in SharePoint 2016, I have refered https://technet.microsoft.com/en-us/library/mt346112(v=office.16).aspx article. Please let me know if there are any alternatives to get this web part functionality working in SharePoint 2016.
