If you made a mistake when changing a configuration item, you need to roll back immediately. ACM supports querying configuration change history and rolling back configurations.


  1. Log on to the ACM console, and select a region as needed in the upper-left corner.
  2. In the left-side navigation pane, select Configurations , enter the Data ID or Group of the configuration to be queried, and then click Search.
    Matching results appear in the list.
  3. In the search results, select More > Historical Versions on the right side of the target configuration.

    The Historical Versions page is displayed.

  4. Perform the following tasks as needed on the page.
    • To view the configuration content of a specific version, click Details in the Actions column.
    • To roll back to a specific version, click Roll Back in the Actions column, and on the Configuration Rollback page, click Roll Back.
    Note ACM currently saves change histories of up to 30 days.
