Import to Jira Cloud is failing due to Duplicated users even though there aren't duplicated users in the source instance.
Cloud -> Cloud
Server -> Cloud
- Generate a backup from a Jira instance(Cloud or Server)
- Import this backup to another Jira Cloud instance.
The import will complete successfully.
The import fails at 90% where in the logs it says that there are duplicated users.
A. Removing all the users from the backup file allow the import to go through.
B. Removing all the users from the target instance also allow the import to go through. For that, reach out to Atlassian Support for assistance.
