Migration of review

Is there a way to migrate the photo review from one product page to another ? Recently we have been modifying our website and converted our variation products to bundle products . So we would like to migrate its corresponding reviews to its bundle product. I have tried export import method for comment. But the images were not getting migrated. I had to manually add them to the migrated review. Please let me know if there is a solution. I believe i am using a free version of the plugin.
