Issue Summary

After migrating a Space from one site to another ( C2C migration) attachments > 200mb are not generating previews on the confluence page. The customer has to explicitly download the file to view the video. This was not the case in their source site where the preview was visible without any issue.

Steps to Reproduce

1. Create a page and add a video file to the page. The thumbnail with the video preview should be visible.
2. Export the space the page created in the previous step and import the space to a different site.

Expected Results

Video Preview should be available on the imported space page.

Actual Results

1. The video preview is not available on the imported space page. Instead a message 'Creating Preview'  is displayed.

Workaround

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