  3. Click the Pattern tab.
  4. Scroll down to the Versions section.
    The state of the active pattern version that Service Mapping and Discovery use is Current.
  5. Click the previous pattern version, which you want to compare to the current version.
  6. Click Compare to Current under Related Links.
  7. In the Compare to Current window, click the Pattern text pane either under Selected Version or Current Version.

    Click the Pattern text pane to open the text comparison window.

    • Deleted line or characters — red
