[rrd-users] rddtool, cacti and device replacement

[bombadil]

Hi,
I am using rrdtool 1.0.46 with cacti 0.8.5 to create bandwidth usage 
graphs for the the ports of my ethernet switch.

One of the port of my switch failed and I am going to replace it with an 
new one, same model and same configuration (I'll copy it over from the 
current switch).

The counter values will start at zero for the new switch.

I don't want to have rrdtool think that the counter wrapped and create 
huge spikes in the graph.

What is the best way to have rrdtool/cacti take into account for the 
device replacement?

Is it feasible at all or should I star over with new rrd database files?

Thanks in advance.
