Upgrade ArcGIS Web Adaptor

To upgrade ArcGIS Web Adaptor, you must uninstall the earlier version, and install the new version. During the installation of the new version, 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 installation of the new version, a warning message appears. You must uninstall the earlier version with the same name to perform the upgrade.

Note that if you are upgrading from version 11.0 and earlier and have multiple instances of Web Adaptor installed, you will see an increase in memory usage. This is because each Web Adaptor instance now requires its own application pool to provide enhanced availability and resiliency.

After installing the new version, you must configure ArcGIS Web Adaptor with its corresponding server site or portal.

Note:

If no administrative account credentials are available to re-register the Web Adaptor with the server site or portal, you can use command line tools to create a temporary administrator account or re-enable the primary site administrator account.
