MRTG uses another program to fill and process the logfiles.  Start it
without any options to see what parameters you can give it.

rateup for mrtg 2.8.9
Usage: ./rateup directory basename [sampletime] [t sampletime]
        [-(t)ransparent] [u|a|g|h|m in out abs_max]
        [i/p file maxvi maxvo max x maxy growright step bits]

Let rateup do the work, just start with the oldest entry you have.  If you
enter the values, rateup will build a logfile for you.

The values are gauge values.
pseudo code:

   while read line from old database
      THEDATE={time sample was taken}
      VALUE1={value to enter}
      VALUE2={value to enter}
      MAXVALUE={maximum possible value}
      rateup /var/tmp  convert  t $THEDATE g $VALUE1 $VALUE2 $MAXVALUE

Perhaps you need to alter something, dunno.  It should be close to a
working solution.
