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.
The short answer here is simple - you should not need to mess around with entityengine.xml

That's the bit that worries me here. If you've followed the instructions, then ALL your data should have been imported and you shouldn't be missing a single issue or project.
I'd start by reading the log from the point at which you started the upgrade - I expect that to be quite long and filled with errors as Jira attempts to upgrade the data.
You seem to be missing the point here. The upgrade documentation you were pointed to earlier is what you need to follow. 4.4.5 to 5.2.11 should be quite straightforward. But you've ignored what was pointed out earlier (messing around with entityengine and the fact you're losing data are indicators that you've not understood the upgrade and you've done something very wrong) and not really given us any more information to work with/
Could you tell us how you are actually getting on with this upgrade instead of asking more questions that don't seem to be helping?
