Dear JIRA Administrators/Developers,
We have a need to upgrade JIRA from version 4.4.5 to 5.2.11 on a Linux environment. Well, it looks like there a lot of JIRA upgrade documents with the various JIRA versions. We have successfully upgraded JIRA according to the specific instructions from this website, https://confluence.atlassian.com/display/JIRA052/Upgrading+JIRA#UpgradingJIRA-upgradingonlinux. However, after the upgrade process, the database data entities from JIRA 4.4.5 are not transferred to 5.2.11, resulting in zero JIRA project. For example, we're hoping that JIRA has the ability of displaying one simple select list of exporting the entityengine.xml from any source version (4.4.5) to any destination version (5.2.11). [JIRA performs the data mapping migration of the database data entities from old to new versions]. We're hoping to find out how to transfer the entityengine.xml from the existing production environment to the upgraded environment. Your help is greatly appreciated.
Thanks,
Kenny
