Exporting Project from Jira Cloud to Jira Server instance - Got error No 'key' field for Issue XXXXX

[Miba]

Hi,

I'm trying to export Jira Cloud Projects (it contain only one project) to Jira server, I know it is tricky but I also followed the instruction from Jira so I supposed it has to work! but I get the error, and yes if I check the entities.xml all the issues do not have Key

There was a problem parsing the backup XML file at /var/atlassian/application-data/jira/import/jira-export.zip: com.atlassian.jira.exception.ParseException: No 'key' field for Issue XXX.

 First, the steps that I've tried from here (link)

1. On Jira Cloud, Settings > Import and Export > Backup Manager > Back up for server (Include attachments, ...)
2. Create a new Jira instance with latest version (docker) with trial license, so I assume Jira Cloud and temporary Jira instance have the same version.
3. On new and empty Jira Instance, Settings > System > Import and Export > Project Import
4. NOW I get the error that I've mentioned above
5. Tried to resolve the issue via these instruction (Removing invalid characters from XML backups) but then this error

6. There was a problem parsing the backup XML file at /var/atlassian/application-data/jira/import/test1.zip: Content is not allowed in prolog.
   

7. I've tried this python code, at least it resolve the issue for the Key part, but now I got:

8. The current version of Jira is at build number '822000', but the supplied backup file was for build number '72002'.

9. so it seems the Cloud version is not the latest!! Is this RIGHT? version 7.2.0 ? I've checked the entities.xml file for version and I found:
10. <OSPropertyString id="10149" value="JIRA"/>
    <OSPropertyString id="13" value="7.2.0"/>
    <OSPropertyString id="1" value="72002"/>

I cannot find Jira instance with version 7.2.0, Is there anything that I've missed here ??
