The version of ArcGIS Web Adaptor must always match the version of Portal for ArcGIS you're using.
ArcGIS Web Adaptor can be installed side by side with other versions. You are not required to uninstall ArcGIS Web Adaptor to install ArcGIS Web Adaptor, and ArcGIS Web Adaptor is not an upgrade of previous releases.
Each ArcGIS Web Adaptor must have its own unique name; you cannot have two Web Adaptors with the same name on a single web server. If a naming conflict is detected during the installation, a warning message is displayed. You must uninstall the earlier version with the same name to resolve the conflict. Alternatively, you can change the name of one of the Web Adaptors to proceed with the installation.
Microsoft Internet Information Server (IIS) is required. For silent installations only, if IIS is not found, the ArcGIS Web Adaptor setup will not proceed. IIS and all necessary components must be installed before installing ArcGIS Web Adaptor silently.
Microsoft .NET Framework 4.5 or later is required. The setup will not proceed if Microsoft .NET Framework 4.5 or later is not found.
In earlier versions, ArcGIS Web Adaptor required Microsoft .NET Framework 3.5 Service Pack 1 (SP1), 4.0, or 4.5 to be installed.
After ArcGIS Web Adaptor is installed, it must be configured. For more information, see Configure ArcGIS Web Adaptor.
Upgrade an earlier version of ArcGIS Web Adaptor
To upgrade an earlier version of ArcGIS Web Adaptor to 10.9, you must uninstall the earlier version, and install the 10.9 setup. During the 10.9 installation, you'll specify the same name as your earlier Web Adaptor. This guarantees your Web Adaptor URL will remain identical to the earlier version.
If a naming conflict is detected during the 10.9 installation, a warning message is displayed. You must uninstall the earlier version with the same name to perform the upgrade.
After installing 10.9, you must configure ArcGIS Web Adaptor with Portal for ArcGIS.
At 10.2 and earlier versions, running the setup upgraded all existing Web Adaptors to the latest version.
Command line parameters for specifying the website and name for ArcGIS Web Adaptor
The following command lines are used for configuring IIS. If these command line parameters are not invoked during a silent installation, the ArcGIS Web Adaptor web application is created under the default website with the default name of arcgis.
This property is required to accept the End User License Agreement during a silent installation. Specify yes to agree to the EULA and install the software. Specifying no or omitting this property will result in a failed installation. The download contains a PDF version of the End User License Agreement (EULA). The EULA.pdf is located in the \Documentation folder.
- WEBSITE_ID=<numeric value of website>
The WEBSITE_ID parameter is used to specify the website where the ArcGIS Web Adaptor web application will be created. The value for WEBSITE_ID is a number specific to each website on your server and assigned by IIS. The IDs for the websites on your server can be found in IIS Manager. The default website has a website ID of 1. By default, the WEBSITE_ID parameter is set to the default website (even if multiple websites exist). The parameter WEBSITE_ID is case sensitive.
- PORT=<port number>
Additionally, if you have a website with multiple ports, use the PORT parameter to install to the specified port of the WEBSITE_ID.
For example, the path is <path to ArcGIS Web Adaptor (IIS) setup download>\setup.exe /qb VDIRNAME=arcgis_external WEBSITE_ID=4059640 PORT=82.
- VDIRNAME=<name of ArcGIS Web Adaptor>
This command line parameter is optional. By default, the VDIRNAME property is set to arcgis. If you do not invoke the VDIRNAME parameter in your command line, the Web Adaptor is created as arcgis. The VDIRNAME parameter is case sensitive. The Web Adaptor name cannot contain spaces.
For example, the path is <path to ArcGIS Web Adaptor (IIS) setup download>\setup.exe /qb ACCEPTEULA=yes VDIRNAME=arcgis_external WEBSITE_ID=4059640.
This optional parameter will allow the setup program to silently configure and install all missing Microsoft IIS components required by ArcGIS Web Adaptor.
