[rrd-users] merge/combine RRD database files

[Martin T]

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


regards,
