I am building a python script that will update some of our mapping services in the middle of the night to prevent any down time.
I also define the service to be an ‘UPDATE’ by modifying the .sddraft XML file with 'esriServiceDefinitionType_Replacement'
My issue is when I update the service all my other services settings are replaced with the defaults. I want to keep the existing configuration of that service in tact and just update the service with a new MXD.
Is there any way to do this using python tools?
