注意：
本教程适合bitbucket的灾难恢复或者服务迁移
前提条件
已经使用bitbucket backup client 做了备份
环境说明
* centos 7
* SQL Server 2012
* Java 1.8
* Bitbucket
old edition - Atlassian Bitbucket v6.3.0
new edition - Atlassian Bitbucket v6.10.0
术语
bitbucket.home 指bitbucket的数据目录
例如： /var/atlassian/application-data/bitbucket
bitbucket 运行目录，指应用目录
例如： /opt/atlassian/bitbucket/[version]
参考文档：
[Using the Bitbucket Server Backup Client](https://confluence.atlassian.com/bitbucketserver/using-the-bitbucket-server-backup-client-776640064.html)
操作步骤：
> 1 - Create a new empty home directory using the user account that will be used to run Bitbucket Server.
```shell
chown atlbitbucket:atlbitbucket /path/to/[bitbucket.home]
```
> 2 - Create the 2 emtpy databases for importing old database and the new one
It should have the configuration described in the ' Create the Bitbucket Server database' section of the relevant page here:
MySQL
Oracle
PostgreSQL
SQL Server
**Even the new one will be retird but it will be used in restore process.**
> 3 - Run the Restore Client. See the following section for details.
here is an exmaple,
```shell
java -Djdbc.override=true -Djdbc.driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" -Djdbc.url="jdbc:sqlserver://192.168.0.22:1433;databaseName=bit2_db;" -Djdbc.user="bit_user" -Djdbc.password="*****" -Dbitbucket.home="/disk2/atlassian/application-data/bitbucket" -jar bitbucket-restore-client.jar /root/bitbucket-20200130-225735-289.tar
```
> 4 - starting to install toally new one of bitbucket
*Install Bitbucket server on the new server by following the instructions on Running the Bitbucket Server installer. Point the installation to an empty directory and install it as a service in case you used to have that in your previous server.*
Make sure your new installation is up and running - refer to Starting and stopping Bitbucket Server. At this stage you should see Bitbucket server guiding you for a configuration from scratch (i.e. it will ask you for license details, admin user etc.) and that's expected.
> 5 -Stop the newly installed instance.
```shell
su - atlbitbucket
cd /opt/atlassian/bitbucket/[version]/bin
sh stop-bitbucket.sh
```
> 6 - rename the new installed HOME directory & rename the old one to the HOME
be careful, change the owner of the HOME directory
```shell
chown atlbitbucket:atlbitbucket /path/to/HOME
```
> 7 - start bitbucket seeing step 5th;
sh start-bitbucket.sh
> 启动后，可能有多种原因无法启动：
1. 在HOME下面的shared bitbucket.properties 数据库连接需要配置为登录到老的数据库
2. 注意： app_property表，与新建的实例的数据库比较，更新为新的实例的一样。
* instance.home
* license
* server.id
再重启，正常了。
