Well, it *seems* your recording data OK so it seems it's only a cosmetic problem with Cacti (e.g. your data is still being collected). Confirm this by checking an rrd:

# cd /usr/local/share/cacti/rra/
# /usr/local/bin/rrdtool dump lan_server_2_hdd_free_74.rrd |grep 2009-07-21

You should see a bunch of non-zero and non-NaN numbers in there covering the data it has collected today.  Feel free to check a few others, as well, like svn-scsc21_hdd_free_587.rrd.

Usually, my biggest problem with upgrading cacti is losing permissions on some or another directory.  Often it's that the user apache runs under php can't access the rra folder.  

What *specific* problem are you having from cacti?  Do you see where the graphs should be but they're broken images?  Do you see graphs with titles but the data is all zero?
