Thank you for reaching out to us on Microsoft Q&A forum.
We deeply appreciate your concerns, and I appreciate the opportunity to clarify the information.
We can't directly change a managed solution to an unmanaged solution in Dynamics 365 (D365). Managed solutions are designed for production environments to ensure that customizations are secure and not easily altered. Unmanaged solutions are used in development environments where changes are frequently made.
Here's what you can do if you need to modify a managed solution:
Export and Recreate:
Export the Managed Solution: First, you need to export the managed solution from your D365 environment. This creates a copy of the solution as managed.
Recreate in Unmanaged Form: Since you can’t directly change a managed solution to unmanaged, you must recreate the solution as unmanaged in a development environment. This involves manually copying the customizations and settings from the managed solution into a new unmanaged solution.
Make Changes: After setting up the unmanaged solution, you can make, and test changes as needed in your development environment.
Repackage: Once you're done with your changes, you need to repackage the updated solution as a managed solution and then import it back into the production environment.
Use Source Code:
If you have access to the original source code or development files for the managed solution, you can use those to create a new unmanaged solution.
Request Assistance:
If the managed solution comes from a third-party vendor, you can contact them for help. They might provide an unmanaged version or offer support for making changes.
Note: Always remember that converting between solution types involves careful planning and testing to ensure that no critical configurations or customizations are lost in the process.
