upgrade help

Hi,

I finally have RAD2007 and am reading all the available
documentation on the DVD and am somewhat ready to
upgrade my BDS2006, albeit with trepidation.

If someone out there can be so kind as to point
out any possible pitfalls when upgrading a BDS2006
system?   Should I just let RAD2007 installation
do it stuff, or should I remove BDS2006 from
the system?

I'm assuming from reading some of these messages,
the DVD-based package I have in front of me is
Update 3, right?

Thanks
