Hi,

I upgraded a crm organization from crm 2011 to crm 2016 on premise. (2011 > 2013 > 2015 > 2015).

After upgrade I cannot import a managed solution to the crm 2016 upgraded organization:

This is the error:

A managed solution cannot overwrite the ConnectionRole component with Id=1ba01ff1-7fc9-e311-88fa-00505694729f which has an unmanaged base instance. The most likely scenario for this error is that an unmanaged solution has installed a new unmanaged ConnectionRole component on the target system, and now a managed solution from the same publisher is trying to install that same ConnectionRole component as managed. This will cause an invalid layering of solutions on the target system and is not allowed.

How can I fix it please ?
