CCMA does not migrate external images

Issue Summary

When using CCMA to migrate Spaces, if a page contains an external image with storage format that appears as:

<ac:image>
<ri:url ri:value="http://confluence.atlassian.com/
images/logo/confluence_48_trans.png" /></ac:image>

The link to the image will be broken in the Cloud preventing the user from seeing the actual image.

Images

Attached image	<ac:image> <ri:attachment ri:filename= "atlassian_logo.gif" /> </ac:image>
External image	<ac:image> <ri:url ri:value="http://confluence.atlassian.com/ images/logo/confluence_48_trans.png" /></ac:image>

 

Steps to Reproduce

1. On Confluence server, Edit a page, select Insert Image or File > add attachment to a page. The attachment will appear with the format:

   <ac:image>
   <ri:attachment ri:filename=
   "atlassian_logo.gif" />
   </ac:image>

2. On Confluence server, copy the image from page 1 and paste it into the Edit screen of page 2.
   Storage format for the image will appear as an external image:

   <ac:image>
   <ri:url ri:value="http://confluence.atlassian.com/
   images/logo/confluence_48_trans.png" /></ac:image>
   

3. Migrate using CCMA

Expected Results

CCMA should migrate both pages and attachments should be visible

Actual Results

Both pages are migrated without errors in the UI. There are also no errors in the logs indicating a problem with external images vs attached image

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
