Install multiple ArcGIS Web Adaptor instances

You can install multiple ArcGIS Web Adaptor instances on the same machine at the same time. The installation can also be repeated on separate machines. The workflows below will guide you through the process.

To install multiple Web Adaptors on the same website (port), they must have different names. For example, two Web Adaptors named arcgis cannot exist on the same website. If you want multiple Web Adaptors with the same name, you must install them on separate websites (ports).

  1. Browse to the downloaded folder containing the ArcGIS Web Adaptor setup, or insert the ArcGIS Server media into the appropriate drive to automatically launch the media front end.
  2. Follow the same instructions that you used to install the first Web Adaptor. For details, see Install ArcGIS Web Adaptor.

The setup detects and prevents any conflicts with the Web Adaptor name. If you see a message indicating that the virtual directory already exists, specify a different name for the Web Adaptor or select a different website.


To apply a Web Adaptor service pack, the base instance cannot be removed.

Install multiple Web Adaptors silently

You can install multiple Web Adaptors by running the setup using command line parameters. See Install ArcGIS Web Adaptor for full instructions on how to use the command line parameters. No additional command line parameters are necessary to install multiple Web Adaptors.
