Migration from jira to zephyr scale

Hi,

My team is currently using Atlassian JIRA v6.0.7 for test case managment. We will be upgrading to Jira cloud and Zephyr scale.

Many of our jira test cases have attachments such pdfs, images, video clips...etc

Is there a way to migrate all of that data? I know there is a way to generate CSV files to import into ZS but we really need the attachments as well.

Any info will be much appreciated.

Thank You
