A new version of ArcGIS Enterprise Cloud Builder for Microsoft Azure is available with each ArcGIS release. An image that contains the latest version of ArcGIS software is also available at each release. The image and ArcGIS Enterprise Cloud Builder for Microsoft Azure versions you use must match. For example, to deploy ArcGIS Enterprise using 11.2 images, you must use the 11.2 version of ArcGIS Enterprise Cloud Builder for Microsoft Azure. Similarly, to deploy from 10.8.1 images, you must use the 10.8.1 version of ArcGIS Enterprise Cloud Builder for Microsoft Azure. You can have different versions of ArcGIS Enterprise Cloud Builder for Microsoft Azure on the same machine, allowing you to manage version-specific deployments.
Beginning with 11.0, you cannot upgrade version 1 (V1) deployments using Cloud Builder. For information on what versions can be upgraded, see Upgrade ArcGIS deployments on Microsoft Azure.
