API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Upgrades a single directory in-place using the PublishedSchemaArn with schema updates found in MinorVersion. Backwards-compatible minor version upgrades are instantaneously available for readers on all objects in the directory. Note: This is a synchronous API call and upgrades only one schema on a given directory per call. To upgrade multiple directories from one schema, you would need to call this API on each directory.


For .NET Core and PCL this operation is only available in asynchronous form. Please refer to UpgradeAppliedSchemaAsync.

Return Value
The response from the UpgradeAppliedSchema service method, as returned by CloudDirectory.


AccessDeniedException Access denied. Check your permissions.
IncompatibleSchemaException Indicates a failure occurred while performing a check for backward compatibility between the specified schema and the schema that is currently applied to the directory.
InternalServiceException Indicates a problem that must be resolved by Amazon Web Services. This might be a transient error in which case you can retry your request until it succeeds. Otherwise, go to the AWS Service Health Dashboard site to see if there are any operational issues with the service.
InvalidArnException Indicates that the provided ARN value is not valid.
InvalidAttachmentException Indicates that an attempt to attach an object with the same link name or to apply a schema with the same name has occurred. Rename the link or the schema and then try again.
ResourceNotFoundException The specified resource could not be found.
RetryableConflictException Occurs when a conflict with a previous successful write is detected. For example, if a write operation occurs on an object and then an attempt is made to read the object using “SERIALIZABLE” consistency, this exception may result. This generally occurs when the previous write did not have time to propagate to the host serving the current request. A retry (with appropriate backoff logic) is the recommended response to this exception.
SchemaAlreadyExistsException Indicates that a schema could not be created due to a naming conflict. Please select a different name and then try again.
ValidationException Indicates that your request is malformed in some manner. See the exception message.
