Updating cacti 0.6.8a to 0.8.x

[cambou]

Hi all,

I'm having trouble updating cacti from 0.6.8a to 0.8.x.
First, I downgrade cacti 0.6.8a to 0.6.8 (because cacti 0.8.1 don't recognize cacti 0.6.8a).

After downgrading, I upgrade cacti 0.6.8 to 0.8.1, the import goes well, all my Devices (100) are there but for the Graphs (447) they are imported but during the import process apprently the rrd file were renamed in cacti's Data sources, for example :

cacti 0.6.8a :
Name : 193.51.43.1_ipsec0_6_in
Internal Data Source Name : 193_51_43_1_ipsec0_

cacti 0.8.1 :
Name : 193.51.43.1_ipsec0_6_in
Data Source Path : <path_rra>/193_51_43_1_193_51_43_1_ipsec0__215.rrd

So on the cacti 0.8.1, no graph were displayed.

(the downgrade from cacti 0.6.8a to 0.6.8 is perfectly working, all the graph are present and well displayed).

Is there a way to properly update cacti 0.6.8 to 0.8.x without aving rra data sources file renamed?
