**2. 白话操作 -Djira.downgrade.allowed=true **

启动的时候加上参数  “ -Djira.downgrade.allowed=true ”

**3. 关闭jira服务 **

[root@iZasdf3qjsdfZ bin]# ./shutdown.sh 
[root@iZasdf3qjsdfZ bin]# ps -ef |grep java
root      3321  3276  0 23:44 pts/0    00:00:00 grep --color=auto java

4 .找到 jira启动目录下修改 setenv.sh 文件 添加如下启动内容即可

[root@iZasdf3qjsdfZ ~]# cd /opt/atlassian/jira/bin/
[root@iZasdf3qjsdfZ bin]# vim setenv.sh
JVM_SUPPORT_RECOMMENDED_ARGS="-Djira.downgrade.allowed=true"

5 .启动服务

[root@iZasdf3qjsdfZ bin]#./startup.sh
