Hi,
I guess I am having a tipical problem with restoring my current Jira data (6.2.3) due starting the older version of Jira (5.0.2) instance without having any backup of Jira_Home directory, which imply that old instance overwrite my current data? The only backup I have is the one from export subdirectory (activeobject.xml and entities.xml).
Is there any chance to restore those data on the server? Because obviously I cannot start now none of the instances. Here is the error message:
An error occurred performing JIRA upgrade
The data before the upgrade has been exported to /atlassian/jira/export/jira_autoexport_20140716_085547.zip 2014-07-16
