Overview

You want to downgrade the Playbooks Managed Solution for MS Dynamics in the event of a problem after updating to the last version.

Information

Dynamics CRM requires some unique considerations when it comes to Source Control. Extensions and customizations made to Dynamics are grouped into what is called a "Solution". Solution files are basically zip files with XML files describing customizations made via the UI such as custom entities, custom fields, or command bar changes. They also contain web resources (i.e. HTML, JS, CSS, files), and plugin assemblies (compiled .NET DLLs). You can't work with solution files directly but Microsoft provides a tool called the SolutionPackager. 

They can be exported to a zip file as either a managed solution or an unmanaged solution to move the changes between CRM organizations/instances.

Managed solutions are what you deploy to a client. They cannot be modified (nor Downgraded, Deleted or Uninstalled) once installed.

• Unmanaged solutions, on the other hand, are worked with during development as they can be modified within the Dynamics CRM UI or via API calls or external tools.
