I’m upgrading a custom product/model from AX2012 R3 CU12 to Dynamics365 using the Lifecycle Services code upgrade service. At the point where uploading the compressed model store, I hit the following error: “Customer models contain no metadata to upgrade. Please make sure the Descriptor folder has valid contents.”
I’ve tried searching online for more information or an explanation of the error, but I can’t find a solution.
I exported the model store again from AX2012 R3 CU12 and uploaded the new (compressed) file. The process completed successfully, so I assume there must have gone something wrong with the first export of the model store.
