Migrating your SonarQube database to another vendor
Customers can download the SonarQube DB Copy Tool.
We provide SonarQube DB Copy Tool to help you migrate your SonarQube database from one database vendor to another. For example, if you've been using your SonarQube instance with Oracle and want to migrate to PostgreSQL, the SonarQube DB Copy Tool will help. DB Copy is preferred for database migration because it does SonarQube-specific checks, ensures data consistency, and outputs meaningful logs.
On this page, source refers to your current database and target refers to the database you are moving to.
1. DB Copy - preparation phase
DB Copy only copies data, not the schema. This is why the purpose of this step is to populate target with an empty SonarQube schema. For this, you have to install a temporary SonarQube instance.
As creating the database schema is a quick operation, you don't need to provision a specific server to do this. A workstation or any non-production server with Java 17 available would be enough.
- Make sure you can connect to your target database.
- Download a SonarQube that matches the version and edition of your source instance.
- Unzip SonarQube and put it in a relevant place on the machine.
- Configure SonarQube to connect to your target database (ie. provide JDBC parameters in the
<sonarqubeHome>/conf/sonar.properties
file). - Start SonarQube using the script matching your operating system:
- On Linux:
<sonarqubeHome>/bin/linux-x86-64/sonar.sh start
- On macOS:
<sonarqubeHome>/bin/macosx-universal-64/sonar.sh start
- On Windows:
<sonarqubeHome>\bin\windows-x86-64\StartSonar.bat
- On Linux:
- Verify that the SonarQube schema was correctly created. To do this, look at the
logs/web.log
file to see the line "Executed DB migrations: success". Once this is done, it means that your target database had been populated with the SonarQube schema. - Stop SonarQube:
- On Linux:
<sonarqubeHome>/bin/linux-x86-64/sonar.sh stop
- On macOS:
<sonarqubeHome>/bin/macosx-universal-64/sonar.sh stop
- On Windows: terminate the
StartSonar.bat
script
- On Linux:
- You can now delete this temporary SonarQube instance.
2. DB Copy - execution phase
Because this step is about copying data from source to target, the overall performance makes a difference. Make sure you execute this on a powerful machine that has fast network access to both database servers.
- Unzip the DB Copy package provided by SonarSource Support on the machine where it will be executed. Java is required.
- Stop the SonarQube instance connected to your source database. This is to ensure that we don't have records being inserted/updated while copying.
- Execute the base command with the correct parameters. See below how to do it.
- If you see something else other than the success message **THE COPY HAS FINISHED SUCCESSFULLY** please open a SonarSource Support ticket and provide the complete DB Copy logs for investigation (logs are just the standard output of the tool).
Base command and parameters
Migrating with an Oracle database
If you wish to migrate with an Oracle database, you need to include the Oracle driver in the classpath so it is available to the sonar-db-copy tool. In this case, the syntax is:
On Windows, the classpath arguments separator is a semicolon (;), while on a Unix system (like in the example) it is a colon (:).
Migrating with all other databases
If you are not migrating from or to an Oracle database, then the syntax is:
Parameter | Description | Required |
-help | Print this help information | no |
-urlSrc JDBC_URL | JDBC URL of the source database | yes |
-userSrc USERNAME | Username of the source database | yes |
-pwdSrc PASSWORD | Password of the source database | yes |
-urlDest JDBC_URL | JDBC URL of the target database | yes |
-userDest USERNAME | Username of the target database | yes |
-pwdDest PASSWORD | Password of the target database | yes |
Here is an example of a copy from an Oracle to a Postgres database. Note that each parameter is on one line and there are \ (backslash) characters to continue the command. While this works on most shell command-line interpreters, it is not necessarily the case. Use only one line and remove backslashes in that case.
