问题
On Debian Jessie I had an installed version of SonarQube 6.2 using Postgresql (latest on Jessie ) Java 8 installed I went through the upgrade process (to v. 6.4)Here
When it came back online all the projects were missing. I can get to them by manually typing in the URL to the project like:
https://[address of server]/dashboard?id=[Name of Project]
Also the in the user admin section (Administration>Security>Users) I see no users. However if I go to groups (Administration>Security>Groups) my sonar user group says it has users. In my case its 14 - but I cannot see any of them. Can anyone help bring this stuff back? I did do a DB back-up before the upgrade - so I can always go back, but I would like to not have to do that.

As answered here, this seems to be a bad ElasticSearch index. Stop your server. Delete $SONARQUBE_HOME/data and restart.
