When I'm trying to convert the existing RRD file to JRB format, I'm getting
the below error msg. 

java -classpath /usr/share/JRobinLite-
org.jrobin.convertor.Convertor /usr/bin/rrdtool /home/test/dns.rrd 
Converting RRDTool files to JRobin native format. 
Original RRDTool files will not be modified in any way 
JRobin files created during the process will have a .jrb suffix 
0001/0002 rrdtool [java.io.IOException: Invalid RRD file] 
0002/0002 dns.rrd [java.io.IOException: Unsupported RRD version (0003)] 
Finished: 2 total, 0 OK, 2 failed 
Conversion took 0.008 sec 
Average per-file conversion time: 0.004 sec 

It's showing as unsupported RRD version. 
I'm using RRDTool version 1.2.23 and the JRobin version is

Any suggestions how to rectify this issue is much appreciated.
