You can leverage this utility to merge the RRDfiles. Although this
has not been tested on 'all' combinations, it should cover the
standard traffic type graphs.<br>

<b>Subject: </b>[rrd-users] merge/combine RRD database files<br>
<br>
I have two RRD database files: old.rrd and new.rrd. According to<br>
"rrdtool info old.rrd" it's a rrd_version = "0001" file and
new.rrd is<br>
a rrd_version = "0003" file. Data source type is COUNTER. Both<br>
databases are used to store router interface counter values.<br>
Is it possible to merge those two files into one? Or at least
generate<br>
graphs based on information from both files?<br>
<br>
<br>
regards,<br>
martin<br>
