 From what I've seen on the lists, I'd be carefull to go that route yet 
with doing a full backup of all data.
Lets say that gvinum has still rough edges. But then those only get 
smoothed out by people taking the leap.

There have also been raports on succes. So I guess the reason nobody 
replied is just because there is no consensus. Also look in the GEOM@ 
archive for several threads on this topic.

For my main fileserver I've stopped at 5.1 at this moment. I need to 
test more before I go there, but I can't seem to find mucht time lately. 
  It that the customers pay the bills for not playing around. :()
