Compare revisions

You can use the Revision History page to preview and compare any two revisions of a map, topic, or ditaval to see the differences between them.

Each revision on the Revision History page is a snapshot of the object at that time. You can preview the content of each revision and compare it to other revisions. You can use this to see how an object changed between revisions.

For example, if you compare revisions of a topic, you can see the content of the topic at each revision. And you can see the highlighted differences in content between the revisions.

You can also compare different revisions of one topic with all the revisions for a clone or another instance of the topic.

To compare revisions:

  1. In the Revision History, click Compare.
    A checkbox is next to each revision.
    Note: If you want to cancel this action, click Compare again.
  2. Select the checkbox for both revisions.
