Hi
we are facing a very weird issue when we try to import issues from one Jira instance to another Jira instance (7.4.0 to 7.3.8).
Everything goes fine and all the issues are imported perfectly with all the fields populated as expected.
But the attachments are not created with correct size. After the import the attachment thumnail shows, the name of the attachment also appears. But the size is different and as such the attachment cannot be opened. So for example in one issue there is .png file which is showing 18 kb on the source Jira server, after the import on the target server it shows as 34 kb.
Has anyone ever faced such issue, and how did you resolve it. Any help will be appreciated. This is a bit urgent for us as we are in the middle of migration of a project.
Regards
