Replace ArcGIS service files while scripting into the server

Question

I have an ArcGIS service into my Portal (10.3), also I have an script that replace directly into the database where those files are stored.

The problem is that when I run the script I see a blend of the past last layer with the new layer.

The output is

output = "C:/arcgisserver/directories/arcgissystem/arcgisinput/pronosticos/pronosticos_db.MapServer/extracted/v101/pronosticos.gdb"

The replacement is made with a simple clic

arcpy.Clip_analysis("gfs_precip_gis_48_"+ date + ".shp", clip, output + "/precipitacion_48horas")

Also I set arcpy.env.overwriteOutput = True

Answer 1
