Hi IT Pros,  


We still get the questions about Internet Explorer migration to Edge Chromium once in a while, especially from Government Agency Customers, the questions usually related to the in-house legacy application’ compatibility and develop tools.  


Today we discuss about all thing migration from IE to Edge, I combine a check list of features, how to run Edge in IE compatible mode and the limitations for your review. We also touch on the new Edge feature Webview2 available in the near future. 


Migrate from IE to Edge check list. 



























































ActiveX control, Silverlight, Java 



Microsoft Edge doesn’t support ActiveX controls or Browser Help Objects (BHOs) like Silverlight or Java. However, if you’re running web apps that use ActiveX controls, BHOs, or legacy document modes on Internet Explorer 11, you can configure them to run in IE mode on the new Microsoft Edge

Edge browser in IE modefeatures and configuration 



Only those sites that you specifically configure (via policy) will use IE mode: 



  • List the site in the Enterprise Mode Site List XML defined in one of these policies: 



  • Microsoft Edge, “Configure the Enterprise Mode Site List” 

  • Internet Explorer, “Use the Enterprise Mode IE website list 

  • The Microsoft Edge site list policy takes precedence over the Internet Explorer site list policy. 



  • All Intranet sites when the Send all intranet sites to Internet Explorer group policy is enabled. 


IE mode supports the following Internet Explorer functionality 



  • All document modes and enterprise modes 

  • ActiveX controls (such as Java or Silverlight) 

  • Browser Helper Objects 

  • Internet Explorer settings and Group Policies that affect the security zone settings and Protected Mode 

  • The F12 developer tools for IE, when launch with IEChooser 

  • Microsoft Edge extensions (Extensions that interact with the IE page content directly are not supported.)

  • Internet Explorer toolbars 

  • Internet Explorer settings and Group Policies that affect the navigation menu (for example – search engines, and home pages.)

Edge feature to auto-redirect from IE to Edge if there is compatible function. 



Many modern websites have designs that are incompatible with Internet Explorer (IE). When an IE user visits an incompatible public website, the user may get a message about incompatible browser. After the message, starting with version 84, automatically redirects users to Microsoft Edge.

IE incompatible banner  




  • A website incompatibility banner is displayed under the address bar for each redirection.  

  • Users may continue to use IE for websites that are not on the IE compatibility list. 

  • Add / Remove Public site in compatible list : email suggestion to ietoedge@microsoft.com

Microsoft Edge supportedbrowser privacy  


with tracking prevention feature.   




  • The tracking prevention feature in Microsoft Edge protects users from online tracking by restricting the ability of trackers to access browser-based storage as well as the network. 

  • To configure, typing in the url address box        edge://settings/privacy. 

  • If any of the visited host names match with a host name on the Disconnectlists of Edge, Microsoft Edge proceeds with evaluating enforcement actions to prevent users from being tracked. 

  • You could set 3 level of prevention as shown here:

Unblock tracking prevention for company’s web developer. 



Microsoft is currently working on the Storage Access API in the Chromium codebase. The Storage Access API gives site developers a way to request storage access from users directly, to quickly and intuitively unblock themselves.

Microsoft Edge exempts a site from tracking prevention when the site is making third-party requests to other sites owned by the same parent organization (as defined in the Disconnect entities.json list) 



Using  Microsoft Edge DevTools to debug Office-Add-in 



When the Office add-in is running in Microsoft Edge, you can use the Microsoft Edge DevTools.

ClickOnce 


DirectInvoke 



Currently, Edge Chromium doesn’t provide native support for ClickOnce or DirectInvoke. 


ClickOnce and DirectInvoke are features available in IE and Microsoft Edge classic (version 45 and earlier) that support the use of a file handler to download files from a website.  


ClickOnce requests are handled by the native file handler in Windows. DirectInvoke requests are handled by a registered file handler specified by the website hosting the file.
