    Device:Raspberry Pi
    System:Raspbian Jessie
    OMV version:3.0.99

    I want to upgrade OMV3.X to OMV4.X on Stretch, and I only want my data history saved,like system information about cpu load average,interfaces and disk usage history.
    other data is not important.

    So,what file should I backup?and migrate it to new OMV4.X?
