The Import button 
on the Service Editor in ArcMap allows you to import the properties of an existing service definition file or published service. Using this method, you avoid manually configuring service properties. Instead, you import the properties of a similar service definition file or published service.
For example, if you publish a map service configured to allow per-request modification of layer order and symbology and you want to publish another map service that uses the same pool of dynamic layers, you can import the properties of your published map service by clicking Import . This saves you the work of manually configuring the properties of your new map service to match the properties of your existing map service.
Note:
To import service properties, the service or service definition file types must match. For example, you cannot import the properties of a map service when publishing a geoprocessing service.
Follow these steps to import service properties from either a service definition file or a published service when you publish a new service:
- Click Import on the Service Editor, which is available when you publish a service in ArcMap.
- On the Import Service Definition dialog box, choose the service type from which you want to import properties.
- Follow these steps to import the properties of a service definition file:
- Choose Import from an existing Service Definition File (*.sd).
- Click the browse button and browse to the service definition file.
- Select the service definition file and click Open.
- Follow these steps to import the properties of a published service:
- Choose Import from a published service.
- Choose the server connection that grants you access to the service from which you want to import properties. If your connection is not in the list, you can create a connection by clicking Add ArcGIS Server
. For more information on how to connect, see Connect to ArcGIS Server from ArcGIS Desktop. - In the services list, select the service from which you want to import service properties.
- Click Import.
Your GIS resource is now configured with the properties of an existing service definition file or published service. You can review these properties by stepping through the tabs of the Service Editor.
Once you confirm the properties are correct, proceed with publishing.
