JIRA是Atlassian公司出品的项目与事务跟踪工具，被广泛应用于缺陷跟踪、客户服务、需求收集、流程审批、任务跟踪、项目跟踪和敏捷管理等工作领域。
公司原来用的是JIRA 3.6.2版本，Atlassian官方已不推荐使用JIRA 4.4之前的版本，之前的版本有漏洞也已不再更新，同事已经安装好了JIRA6.0.8版本，新版的JIRA界面扁平化设计，支持移动端浏览，很符合移动互联网企业的风格，现在JIRA升级到了新的版本JIRA 6.1.7，但是在迁移数据的时候，直接从3.6.2迁移到6.0.8失败，google了很久，才发现需要在4.4.5上面将数据转换一下，在此记录一下数据迁移步骤。
思路：（1），安装Jira4.4.5；（2），将Jira3.6.2的数据导入到Jira4.4.5后再导出；（3），再将从4.4.5导出的数据导入到6.0.8版本中，这样就完成了数据的迁移工作，升级也完成了。
准备工作，JIRA3.6.2以及JIRA6.0.8已经安装，还需要安装的是中间的过度版本4.4.5

3，Jira4.4.5配置过程
安装完后可以直接访问:8080/，进行Jira配置步骤。
3.1，访问报错问题
如果访问出现该页面，是因为我们还没有配置JIRA HOME的路径，需要设置Java_home路径，先去查看下JAVA_HOME路径为：
[root@name01 atlassian-jira-4.4.5-standalone]# echo $JAVA_HOME
/usr/lib/jvm/jdk1.7.0_60
[root@name01 atlassian-jira-4.4.5-standalone]#
找到jira的配置文件
[root@name01 atlassian-jira-4.4.5-standalone]# find /root/atlassian-jira-4.4.5-standalone -name jira-application.properties
/root/atlassian-jira-4.4.5-standalone/atlassian-jira/WEB-INF/classes/jira-application.properties
[root@name01 atlassian-jira-4.4.5-standalone]#
[root@name01 atlassian-jira-4.4.5-standalone]# vim /root/atlassian-jira-4.4.5-standalone/atlassian-jira/WEB-INF/classes/jira-application.properties
# Do not modify this file unless instructed. It is here to store the location of the JIRA home directory only and is typically written to by the installer.
jira.home = /usr/lib/jvm/jdk1.7.0_60
在jira.home = 后面添加上JAVA_HOME的路径，保存配置文件后再重启JIRA。
3.2，配置好jira.home后重启Jira
[root@name01 atlassian-jira-4.4.5-standalone]# /root/atlassian-jira-4.4.5-standalone/bin/shutdown.sh
