Notes:
    currently it checks for lt 9.0.0~12. should it only be applied to a
    later version, don't forget to adapt the version check!
    
    I tested it by bumping the version to 9.0.0~12
    upgraded to it -> migration ran
    reinstalled -> no migration happening
    
    when installing the bumped pve-manager package and the
    proxmox-rrd-migration-tool package at the same time, dependencies are
    resolved and the postinst script works.
    
    There is still one bug though that happens on my live system: While the
    migration tool moves the processed files to FILE.old, new ones without
    the .old are still present.
    I did a quick try, disabling rrdached before we call the migration tool.
    But that didn't help. Could be that pmxcfs is receiving new data and is
    recreating them. Or maybe something else.
    That would need to be debugged to figure out as apparently I did miss
    something here regarding the behavior.
