Below is the scenario we face :
* Migrated a project from on-prem to cloud, out of which a few issues failed
* Manually exported those issues via CSV from the on-prem instance and imported them to the Cloud instance
* Due to security concerns we cannot open the On-prem instance to external access so the Attachments dont get imported via the url in the CSV
I tried to run the "Migrate to Cloud" with "Attachments Only" for that one project but that didn't work as well.
