 <h3>Method Details</h3>
 <div class="method">
+    <code class="details" id="checkUpgrade">checkUpgrade(environment, body=None, x__xgafv=None)</code>
+  <pre>Check if an upgrade operation on the environment will succeed. In case of problems detailed info can be found in the returned Operation.
+
+Args:
+  environment: string, The resource name of the environment to check upgrade for, in the form: &quot;projects/{projectId}/locations/{locationId}/environments/{environmentId}&quot; (required)
+  body: object, The request body.
+    The object takes the form of:
+
+{ # Request to check whether image upgrade will succeed.
+  &quot;imageVersion&quot;: &quot;A String&quot;, # The version of the software running in the environment. This encapsulates both the version of Cloud Composer functionality and the version of Apache Airflow. It must match the regular expression `composer-([0-9]+\.[0-9]+\.[0-9]+|latest)-airflow-[0-9]+\.[0-9]+(\.[0-9]+.*)?`. When used as input, the server also checks if the provided version is supported and denies the request for an unsupported version. The Cloud Composer portion of the version is a [semantic version](https://semver.org) or `latest`. When the patch version is omitted, the current Cloud Composer patch version is selected. When `latest` is provided instead of an explicit version number, the server replaces `latest` with the current Cloud Composer version and stores that version number in the same field. The portion of the image version that follows `airflow-` is an official Apache Airflow repository [release name](https://github.com/apache/incubator-airflow/releases). See also [Version List] (/composer/docs/concepts/versioning/composer-versions).
+}
+
+  x__xgafv: string, V1 error format.
+    Allowed values
+      1 - v1 error format
+      2 - v2 error format
+
+Returns:
+  An object of the form:
+
+    { # This resource represents a long-running operation that is the result of a network API call.
+  &quot;done&quot;: True or False, # If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
+  &quot;error&quot;: { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors). # The error result of the operation in case of failure or cancellation.
+    &quot;code&quot;: 42, # The status code, which should be an enum value of google.rpc.Code.
+    &quot;details&quot;: [ # A list of messages that carry the error details. There is a common set of message types for APIs to use.
+      {
+        &quot;a_key&quot;: &quot;&quot;, # Properties of the object. Contains field @type with type URL.
+      },
+    ],
+    &quot;message&quot;: &quot;A String&quot;, # A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.
+  },
+  &quot;metadata&quot;: { # Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.
+    &quot;a_key&quot;: &quot;&quot;, # Properties of the object. Contains field @type with type URL.
+  },
+  &quot;name&quot;: &quot;A String&quot;, # The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`.
+  &quot;response&quot;: { # The normal response of the operation in case of success. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`.
+    &quot;a_key&quot;: &quot;&quot;, # Properties of the object. Contains field @type with type URL.
