前言：
JIRA是Atlassian公司出品的項目與事務跟蹤工具，被廣泛應用於缺陷跟蹤、客戶服務、需求收集、流程審批、任務跟蹤、項目跟蹤和敏捷管理等工作領域。
公司原來用的是JIRA 3.6.2版本，Atlassian官方已不推薦使用JIRA 4.4之前的版本，之前的版本有漏洞也已不再更新，同事已經安裝好了JIRA6.0.8版本，新版的JIRA界面扁平化設計，支持移動端浏覽，很符合移動互聯網企業的風格，現在JIRA升級到了新的版本JIRA 6.1.7，但是在遷移數據的時候，直接從3.6.2遷移到6.0.8失敗，google了很久，才發現需要在4.4.5上面將數據轉換一下，在此記錄一下數據遷移步驟。
思路：（1），安裝Jira4.4.5；（2），將Jira3.6.2的數據導入到Jira4.4.5後再導出；（3），再將從4.4.5導出的數據導入到6.0.8版本中，這樣就完成了數據的遷移工作，升級也完成了。
准備工作，JIRA3.6.2以及JIRA6.0.8已經安裝，還需要安裝的是中間的過度版本4.4.5

3，Jira4.4.5配置過程
安裝完後可以直接訪問http://192.168.171.230:8080/，進行Jira配置步驟。
3.1，訪問報錯問題
如果訪問出現該頁面，是因為我們還沒有配置JIRA HOME的路徑，需要設置java_home路徑，先去查看下JAVA_HOME路徑為：
[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 = 後面添加上JAVA_HOME的路徑，保存配置文件後再重啟JIRA。
3.2，配置好jira.home後重啟Jira
[root@name01 atlassian-jira-4.4.5-standalone]# /root/atlassian-jira-4.4.5-standalone/bin/shutdown.sh
