Today I have installed Sonarqube 5.1.1. Not having a lot of data/projects I'm using the H2 db embedded in Sonarqube.
Following the steps in the Upgrading page of the Sonarqube documentation I have the process up and running but without any data.
Copying the \data\es folder from the old installation to the new one create a lot of failed to add mapping WARN on the log file and end with the process being stopped.
The old installation is in the folder sonarqube-4.5.1 in the root of my D disk, the new installation is in the folder sonarqube-5.1.1 on the same disk.
What I'm supposed to do to copy the current H2 data to the new installation?
H2 DB upgrade is not supported. As you can see at the bottom of each page of your running SonarQube instance, H2 must be used only for testing purposes.
