CommentReaction error while exporting a Jira Project

[Martin Benavides]

Hi legends,

I am requesting your help on trying to solve this import project issue. I created a dummy project to test the exportation of project from one instance to other on Jira Data Center. This project only contains 2 issues without any comment at all and still facing this error.

Data import for project with key: TMP
There was an unexpected problem processing the backup XML file at /opt/atlassian/jira/temp/com.awnaba.projectconfigurator1638816701664/data/data.zip: org.ofbiz.core.entity.GenericModelException: Could not find definition for entity name CommentReaction
INFO  13:18:42,142 Project Import: Parsing the backup file '/opt/atlassian/jira/temp/com.awnaba.projectconfigurator1638816701664/data/data.zip' to obtain a Backup Overview.
ERROR 13:21:26,933 There was an unexpected problem processing the file '/opt/atlassian/jira/temp/com.awnaba.projectconfigurator1638816701664/data/data.zip' when performing a project import.

Does anyone know what could be happening?

I appreciate any advice. 

Thank you

Martin B.

Solved.

Even that Project Configurator gives you the "import on different versions" option, without having same versions on instances, looks like it will never work.

Cheers.
