Symptoms

After you migrate the sites on Microsoft SharePoint Server 2013 to SharePoint Server 2016, the following web part controls no longer work on the migrated sites:

Cause

These web part controls were replaced by new versions in SharePoint Server 2016.

To do this, add the following entries in the web.config file for the migrated Web Apps.

SpListFilterWebPart

<SafeControl Assembly="Microsoft.SharePoint.Portal, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.SharePoint.Portal.WebControls" TypeName="SpListFilterWebPart" Safe="True" />

ExcelWebRenderer

<dependentAssembly>   
 <assemblyIdentity name="Microsoft.Office.Excel.WebUI" publicKeyToken="71e9bce111e9429c" />   
 <!-- Assembly versions can be redirected in application, publisher policy, or machine configuration files. -->   
 <bindingRedirect oldVersion="15.0.0.0" newVersion="16.0.0.0"/>   
 </dependentAssembly>
