Saved system information while upgrading

  • origin:
    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?

  • I found /var/log wrote "/var/lib/rrdcached/db/localhost/**.rrd"
    so,I backup /var/lib/rrdcached/db/localhost folder,and move them to the new OMV4.x
    That‘s fine.
