      I would like to try to edit my database to get some older data for other purposes and then reduce file size.
      Unfortunately I could not find any data when opening the file on another machine.
      I tried H2 commandline tool and SQL Workbench on Windows after copying the big mycontroller database to this machine.
      Could you give a hint on a setup you might be using for debugging and on the db structure, e.g. where to find the sensor data?

          Thanks, was looking for that. Also Cimba007 explained the steps at https://github.com/mycontroller-org/mycontroller/issues/392

          Still it won't work here likely because I can't find the correct version of h2.
          I'm still running 0.0.3.Final-SNAPSHOT with db 1.03.03 - 2016 Sep 20

          I tried to upgrade, but backup fails (400: Bad Request Database backup failed!).
          I tried to find mentioned db version, the newest from 1.3 branch (1.3.176) did seem to open the db but showed no user or metrics tables.

          Can I convert it somehow to the new version and also fix the index issue Cimba007 explained (I'm suffering very slow UI even running the server on a decent workstation)?

          logfile:

            @ragflyer I have fixed @cimba007 solution. yet to fix it fully.
            Your log says something like your trying on the corrupted database. can you copy the running database and try again. Kindly do a backup before any actions.
            I will try to publish json API. We can use it anywhere.
