There is no need to obtain and install each previously released version in sequence or to uninstall your previous version of Portal for ArcGIS.

If you are at version 10.7 or later, running the Portal for ArcGIS 11.1 setup automatically upgrades your portal to 11.1.

Read the upgrade documentation for the interim version to confirm direct upgrades are supported for the Portal for ArcGIS version you start with. To upgrade Portal for ArcGIS 10.6.1 or earlier, first upgrade it to an interim version (10.7.x - 10.9.x) and then upgrade that version to 11.1.

Upgrading directly to Portal for ArcGIS 11.1 from versions 10.6.1 or earlier is not supported.

Ensure the new license file is adequate for your current user and app configuration. The license file you input during the upgrade is used to license your portal's users and apps. Note that two Web Adaptors with the same context cannot be installed on the same machine. To do this, uninstall the Web Adaptor currently configured with your portal, and then install the 11.1 Web Adaptor with the same name used previously.

You must keep the same Web Adaptor context when upgrading.

For example, you can retain your 10.5 version of ArcGIS Web Adaptor (IIS) and install 11.1 on the same web server.

If you cannot update your current Web Adaptor, you can alternatively install a 11.1 version of ArcGIS Web Adaptor (IIS) alongside your previous version on the same machine.

If your portal is currently in read-only mode, turn the mode off before running the upgrade.

If the ArcGIS Server site you've federated with the portal includes multiple machines, upgrade your GIS servers sequentially.

You don't need to upgrade ArcGIS Pro at the same time as ArcGIS Enterprise.

The version of all base ArcGIS Enterprise components must be the same.

The time it takes to complete the upgrade varies, depending on how much content your portal contains and how many accounts are registered, as well as how many components and customizations you deploy.

Prepare to upgradeīefore upgrading, carefully review the following information: Upgrade concepts The Portal for ArcGIS 11.1 setup is designed to detect and upgrade an existing installation of Portal for ArcGIS.

Perform an upgrade of your portal deployment.
