How you upgrade or apply patches to existing deployments depends on how you created the deployment and what software version you're using.
Upgrade to 10.9
To upgrade to 10.9, you can upgrade the deployment the same way you would upgrade on-premises software or, if you created the deployment using a 10.8 or 10.8.1 CloudFormation template provided by Esri, you can use a Chef script to upgrade to 10.9.
See the upgrade topics for each deployment for instructions:
- ArcGIS Enterprise on a single Amazon Elastic Compute Cloud (EC2) instance
- ArcGIS Enterprise on two EC2 instances
- An ArcGIS Server site (includes ArcGIS GIS Server, ArcGIS GeoAnalytics Server, and ArcGIS Image Server sites)
- A spatiotemporal big data store
- ArcGIS GeoEvent Server
- ArcGIS Mission Server
- ArcGIS Notebook Server
Apply patches
A patch notification tool (patchnotification) is included with ArcGIS software 10.3 and later. It is in the tools directory of each ArcGIS component's installation directory. From 10.3 to 10.6, the tool returns a list of required patches and provides a link to a page that allows you to download the patches. The 10.6.1 and later patch notification tool lists and installs the patches. However, for 10.6.1, 10.7.x, and 10.8 deployments, you must install patches one at a time. On 10.8.1 deployments, you can apply patches in bulk when components are installed on the same Amazon Elastic Compute Cloud (EC2) instance.
Before applying patches, you should always read their descriptions. You can find these on the Downloads page of the Esri support website.
Back up before upgrading
Before you upgrade an ArcGIS Enterprise deployment or apply patches, use the webgisdr tool installed with Portal for ArcGIS to create a backup of the ArcGIS Enterprise components. This backup allows you to restore your deployment using the same URLs if you encounter issues that require you to revert to your old deployment.
Note:
If you have a spatiotemporal big data store in your deployment, use the ArcGIS Data Store backupdatastore utility to create a backup of it, as it is not included in the backup created by the webgisdr tool.
Before you upgrade a stand-alone ArcGIS Server site, create a backup of the site.
