This is unfortunately a design issue in Torrus. Datasources are 
referenced by name (usually the name in the SNMP MIB) in the RRD file. 
With new versions of Torrus, some names might change (i.e. in your case 
ifInOctets -> ifHCOutUcastPkts indicating the move from 32bit to 64bit 
SNMP counters), some might be removed or added, but the datasources 
present in the RRD are not changed.

If you value your data you can try to export it using rrdtool dump, 
change the DS names and reimport it using rrdtool import, but that is 
quite cumbersome. If you don't, just delete the corresponding .rrd-File.
