Saving task settings - AWS Database Migration Service

Saving task settings

You can save task settings as a JSON file in case you want to reuse the settings for another task. You can find tasks settings to copy to a JSON file under the Overview details section of a task.

Note

While reusing task settings for other tasks, remove any CloudWatchLogGroup and CloudWatchLogStream attributes. Otherwise, the following error is given: SYSTEM ERROR MESSAGE:Task Settings CloudWatchLogGroup or CloudWatchLogStream cannot be set on create.

For example, the following JSON file contains settings saved for a task.
