It IS possible to 're-aggregate' the data from the old file into the
new file if you write a custom script to do it. By its nature, it's
not a perfect transfer (e.g. if you had steps=12 before and you have
steps=20 now, and you have a sample that had 1 lost packet, do you
scale up to 2 lost packets or down to 1 in the new data? Both
results skew your percentages. Plus, for the older samples, you're
aggregating an aggregate, which itself loses accuracy...) but at
least it gives you SOME kind of historical basis.<br>
<br>
This approach can also be a significant amount of work as (AFAIK) no
one has released a ready-made script to do it. I've never been
attached to my history enough to bother, and I try not to change my
database settings after it's running anyways.<br>
<br>
If you're really, really tied to your history and want to put the
work into it, it is possible, however.<br>

<div>You could just back up the data, but I don't believe it has
any raw data, just RRD files, which you would have to generate
the graphs for yourself.</div>

Hi,<br>
<br>
If I make a change to the "steps" of a probe, is there a way
to save<br>
and reference historical information? I know when you
change the step<br>
value, you have to delete the data as it doesn't match up
with the<br>
historical information.<br>
<br>
Thanks,<br>
Stefano<br>
