That's exactly what I'm doing now. I have a 0.19 system that's been  
running for almost a year. I set up a second box running 0.20 and I'm  
checking it out to see if there are any problems before I switch over.

I hesitated to suggest this method though, as it requires not only a  
complete spare machine with RAM, drives, CPU, mobo, video card etc.  
but also spare capture devices. Not everyone has piles of old  
hardware just sitting around.

It also doubles the load I'm putting on DataDirect. I'm not sure if  
that bothers them or not, I never have understood their business  
model. Obviously I could dope out a way to just connect to the DB in  
my live machine but the upgrade in MySQL etc. is part of the total  
upgrade and it's just easier to set up a complete spare.

This is really just to protect me against the inevitable failure of  
the 0.19 system, so far I haven't found anything in 0.20 that would  
cause me to upgrade - some "nice" features but nothing to be worth  
the bother to upgrade unless I have to, others may feel differently  
of course.
