Include functionality that currently exists in ArcMap to import an existing Service Definition (.sd) file.
Importing a SD file allows users to re-publish an existing service and pull in the existing properties of that service (including all of the parameters and descriptions).
Currently, overwriting the service requires re-inputting the parameters and descriptions.
This ArcGIS Idea is related, and could potentially provide a workflow, but only if there is functionality to import the existing details of a service during the overwrite process:
