Depending on what your requirements for "production" might be and how 
good know FreeBSD, this is a good enough path. The officially 
recommended one also includes 6.4, but if the configuration is simple 
enough (no fancy partitioning, no software RAID), you could simply skip 
from 6.2RC1 all the way to 8.0 if you know what you are doing.

Regardless, you will need to upgrade all of the installed ports (you can 
do it at the end, no need to upgrade every time).

In any case, don't do it remotely (without access to a physical 
console), this is a long upgrade path for it to simply work the first 
time. As others said, you can recover FreeBSD from practically any 
disaster involving such an upgrade, but it won't necessarily be easy.
