"Cannot create a file when that file already exists" during data upgrade from AX 2012 to Dynamics 365 for Finance and Operations

During the data upgrade of an AX 2012 R2 to Dynamics 365 for Finance and Operations I had the following errors when running the "DataUpgrade-Package" at step 9:

Error during AOS start: Cannot create a file when that file already exists.

In my case, restarting the environment hosted on Azure and restarting the step helped.

These post applies to following version:
