Prepare your solutions for the update
Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online contain a number of exciting changes. To take advantage of new features, you need to ensure any customizations are compatible with this new version. With the launch of these versions, we are officially dropping support for legacy Microsoft Dynamics CRM 4.0 features.
Microsoft Dynamics CRM 4.0 features that will no longer be supported:
CRM 4.0 plug-in
CRM 4.0 client-side scripting
CRM 4.0 custom workflow activities
CRM 4.0 web service API (also known as the 2007 web service endpoints)
ISV folder support for custom web applications
To assist you in this effort, we created a tool to help you identify and correct unsupported code prior to your upgrade. Please download, install, and run the tools below on your Microsoft Dynamics CRM 2011 organization.
For information on how to fix the issues found by this tool, see Upgrade scripts to Microsoft Dynamics CRM 2013.
The Solution Down-level utility, specifically built for the Microsoft Dynamics CRM December 2012 Service Update, is not provided in the Microsoft Dynamics CRM 2013 and Microsoft Dynamics CRM Online SDK. Due to improvements to the solution framework, this tool is no longer needed.
