You can use the SonarQube MySQL Database Migrator to copy your SonarQube database from your MySQL (source) database to a non-MySQL (target) database.

• SonarQube version 6.7LTS to 7.8
  Note: Your source and target databases must be using the same version of SonarQube.
• Currently using MySQL

Warning: do not run migration on live SonarQube instances.

To copy your SonarQube database from your source database to the target database, follow these steps:

1. Download the latest release of the migrator and unzip it.

2. Start then stop the same version of SonarQube that you're running on your source database on your target database. For example, if you're running SonarQube 7.3 on your source database, run then stop SonarQube 7.3 on your target database.

3. Delete the Elasticsearch data folder in the target SonarQube instance: data/es5 on SonarQube 6.7-7.6 and data/es6 on SonarQube 7.7 and above.

4. Run the migrator with -help to get usage instructions.

Required parameters:

• -source PATH where PATH is the path to the configuration file of your SonarQube instance running MySQL.
• -target PATH where PATH is the path to the configuration file of your SonarQube instance running a non-MySQL database.

Note: The source database must be a MySQL database, and the target database must be a non-MySQL database.

The configuration files use the same format as sonar.properties file in a SonarQube installation, and you can even directly use the path to a sonar.properties file of a SonarQube instance. Your configuration files should be formatted as follows:

sonar.jdbc.url = jdbc:mysql://localhost:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true&useConfigs=maxPerformance&useSSL=false
sonar.jdbc.username = sonar
sonar.jdbc.password = sonar

The migrator performs various sanity checks before copying data and prints diagnostics about its progress. It stops on the first error. Read the error messages carefully.

The Oracle database driver is not included in the distribution, so you must provide it yourself.

Please download the JDBC driver for Oracle and copy it to the mysql-migrator/lib directory in the unzipped folder of the migration tool. The file must be named oracle.jar exactly.

With the Java driver in place, follow the steps above to migrate just like any other database.
