同系统同域名同hostname异机恢复：
原主机192.168.10.234，新主机192.168.10.231
192.168.10.234上的操作
1.先备份原系统数据：
备份ldap信息
[zimbra@test6 ~]$ ldapsearch -h 192.168.10.234 -x -D "uid=zimbra,cn=admins,cn=zimbra" -w GdpHujkAkr > /opt/zimbra/backup/20170815.ldap.bak
备份邮件内容以及mysql索引文件
[zimbra@test6 ~]$ mkdir /opt/zimbra/backup/store
[zimbra@test6 ~]$ cp -r /opt/zimbra/store/* /opt/zimbra/backup/store/
[zimbra@test6 ~]$ mkdir /opt/zimbra/backup/index
[zimbra@test6 ~]$ cp -r /opt/zimbra/index/* /opt/zimbra/backup/index/
备份密码信息
[zimbra@test6 ~]$ zmlocalconfig -s |grep password > /opt/zimbra/backup/password.bak
备份mysql信息
[zimbra@test6 ~]$ netstat -anp|grep 7306
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:7306 0.0.0.0:* LISTEN 21106/mysqld

[zimbra@test6 ~]$ ps -ef |grep 21106

zimbra 25074 9790 0 09:45 pts/1 00:00:00 grep 21106

停止zimbra
更改DNS指向192.168.10.231
[root@test6 zcs]# vim /var/named/chroot/var/named/benet.zx
:1,$s/234/231/gi
[root@test6 zcs]# vim /var/named/chroot/var/named/benet.fx
:1,$s/234/231/gi
[root@test6 zcs]# service named restart
192.168.10.231上的操作
更改hosts文件，更改dns服务器，关闭sendmail服务、关闭httpd服务，安装zimbra。
测试是否能够正常使用
将192.168.10.234backup目录内容拷贝到192.168.10.231的/opt/zimbra/backup目录下，注意权限
[root@test6 ~]# cd /opt/zimbra/backup/
[root@test6 backup]# chown -R zimbra.zimbra *
更改mysql相关密码：
[zimbra@test6 backup]$ zmmypasswd --root 0FH4ILTDaJWBj.TJSeEtzTsRt67XHv
/opt/zimbra/bin/mysqladmin -u root --password=PeMOvjHp9Ac39L18b5DEdj93g password 0FH4ILTDaJWBj.TJSeEtzTsRt67XHv
* Changed mysql root user password
* Changed mysql root user password root@localhost
[zimbra@test6 backup]$ zmmypasswd RLv1g95JH44VRfBF3SmzaF5E_rP_odR
* Changed zimbra mysql user password
测试mysql登录
[zimbra@test6 backup]$ mysql -uroot -p0FH4ILTDaJWBj.TJSeEtzTsRt67XHv

备份mysql信息
[zimbra@test6 backup]$ mkdir /opt/zimbra/backup/mysql.old
[zimbra@test6 backup]$ /opt/zimbra/mysql/bin/mysqldump -u root -p0FH4ILTDaJWBj.TJSeEtzTsRt67XHv --socket=/opt/zimbra/db/mysql.sock --opt -R --all-databases > /opt/zimbra/backup/mysql.old/20170815.sql
恢复store、index目录：
[zimbra@test6 backup]$ mkdir /opt/zimbra/backup/store.old
[zimbra@test6 backup]$ mkdir /opt/zimbra/backup/index.old
[zimbra@test6 backup]$ mv /opt/zimbra/store/* /opt/zimbra/backup/store.old/
[zimbra@test6 backup]$ mv /opt/zimbra/index/* /opt/zimbra/backup/index.old/
[zimbra@test6 backup]$ cp -r /opt/zimbra/backup/store/* /opt/zimbra/store
[zimbra@test6 backup]$ cp -r /opt/zimbra/backup/index/* /opt/zimbra/index/
恢复mysql信息;
[zimbra@test6 backup]$ mysql -u root -p0FH4ILTDaJWBj.TJSeEtzTsRt67XHv < /opt/zimbra/backup/zimbra.dump.20170815.sql
恢复ldap信息：
[zimbra@test6 backup]$ ldapadd -h 192.168.10.231 -x -c -D "uid=zimbra,cn=admins,cn=zimbra" -w dOQnGXv1nf < /opt/zimbra/backup/20170815.ldap.bak
重启zimbra;
[zimbra@test6 backup]$ zmcontrol restart
登录测试：https://192.168.10.231:7071/zimbraAdmin/
用OutLook连接提示错误：
-ERR only valid after entering TLS mode
原因：Zimbra默认不允许在使用非加密传输时进行身份认证，需要关闭相关安全设置。
在Zimbra上切换至zimbra用户，执行如下命令：
zmprov ms `zmhostname` zimbraImapCleartextLoginEnabled TRUE
zmprov ms `zmhostname` zimbraPop3CleartextLoginEnabled TRUE
zmprov ms `zmhostname` zimbraMtaTlsAuthOnly FALSE
zmhostname 名字是写死的，不能错。修改时以上命令不用改动。
重新启动Zimbra服务后试试OutLook是否可以接收邮件了（测试过程没有重启zimbra也一样能收到）
如果没有合法域名，请修改本地hosts文件，以便测试foxmail或outlook添加邮箱

====================================================================================================================================
恢复方法二（推荐）：直接拷贝store、index、数据库data目录、导出ldap-config、ldap、修改localconfig.xml密码。
在新服务器上安装zimbra，服务器主机名，域名管理员密码、dns服务器地址等都设置为一样的。
在旧服务器上用root用户创建/backup目录：
mkdir -p /backup/ldap
chown -R zimbra.zimbra /backup
su - zimbra
zmcontrol stop
/opt/zimbra/libexec/zmslapcat -c /backup/ldap备份LDAP配置数据库
/opt/zimbra/libexec/zmslapcat /backup/ldap备份LDAP数据
cp -a /opt/zimbra/data/ldap/hdb/db/DB_CONFIG /backup/ldap/
zmlocalconfig -x -s |grep password > /backup/password.bak密码备份
zmlocalconfig -n （查看其它设定值）
zmlocalconfig -e [attribute-name]='[attribute-value]'（如果有其他设定值，在新服务器上执行此命令设定）
cd /opt/zimbra/db/data/备份数据库文件
tar -pzcvf /backup/mysql_data.tar.gz ./
cd /opt/zimbra/store/
tar -pzcvf /backup/store.tar.gz ./备份邮件
cd /opt/zimbra/index/备份索引
tar -pzcvf /backup/index.tar.gz ./
切换到root身份
cd /backup/
tar -pzcvf /tmp/backup.tar.gz ./
scp /tmp/backup.tar.gz 192.168.10.231:/backup/
在新的服务器上安装完zimbra：
mkdir -p /backup/old/{ldap,index,store,mysql_data}
chown -R zimbra.zimbra /backup
su - zimbra
zmcontrol stop
mv -f /opt/zimbra/data/ldap/config/* /backup/old/ldap/备份新服务器的LADP配置信息与数据
mv -f /opt/zimbra/data/ldap/hdb/* /backup/old/ldap/
mkdir -p /opt/zimbra/data/ldap/hdb/db /opt/zimbra/data/ldap/hdb/logs创建新的LDAP相关目录
cd /backup/
tar -zxvf backup.tar.gz
cp -a /backup/ldap/DB_CONFIG /opt/zimbra/data/ldap/hdb/db/
chown -R zimbra:zimbra /opt/zimbra/data/ldap（root执行）
/opt/zimbra/openldap/sbin/slapadd -q -n 0 -F /opt/zimbra/data/ldap/config -cv -l /backup/ldap/ldap-config.bak导入LDAP配置信息
/opt/zimbra/openldap/sbin/slapadd -q -b "" -F /opt/zimbra/data/ldap/config -cv -l /backup/ldap/ldap.bak导入LDAP数据库信息
修改localconfig.xml文件中以下密码：
a. zimbra_mysql_password
b. mysql_root_password
c. zimbra_logger_mysql_password (Note: Transfer/copy this value to the New Server only if available from the old Old Server.)
d. zimbra_ldap_password
e. ldap_root_password
f. ldap_postfix_password
g. ldap_amavis_password
h. ldap_nginx_password
i. ldap_replication_password
zmlocalconfig -x -s |grep password查看密码
vim /opt/zimbra/conf/localconfig.xml
1,$s/新服务器密码/旧服务器密码/gc按Y确认更换
mv -f /opt/zimbra/db/data/* /backup/old/mysql_data/
mv -f /opt/zimbra/store/* /backup/old/store/
mv -f /opt/zimbra/index/* /backup/old/index/
cd /opt/zimbra/db/data/
tar -zxvf /backup/mysql_data.tar.gz
tar -zxvf /backup/store.tar.gz -C /opt/zimbra/store/
tar -zxvf /backup/index.tar.gz -C /opt/zimbra/index/
zmcontrol start
