woh you have just over complicated the entire process
i see how vB manage to scam chumps into paying $150 for setup
CF wil be down for a max of an hour, depending on how fast david can upload the files and in general move
vB works the exaxt same way it always has just with alot more features, so what if a few more links apear doesnt matter, for as long as there have been humans there have been explorers
risk of database corruption is a yes but low seeing as you made the mistake of staying on an unstable un support beta, your no more at risj upgrading than you are remaining on what you are atm, but to combat this god create database backups
why on earth would you need a second server? your not even using an inch of the server you on atm why a second one, i think you have missed how the upgrade works
EDIT: your only upgrading to vb3.0.7 well then most of the risks involved have just gone, i thought you were going for 3.5
