Going from FreeBSD 5.x to DragonFly

[Bryan Berch]

I hope this is the right place to ask these questions, if not, direct me 
elsewhere.

Am I correct that it is now possible to go from Freebsd 5.x to DragonFly 
and not need to install 4.x by follow the steps in /src/UPDATING version 
1.7?  My dialup connection makes moving to  DragonFly impossible otherwise.

Also I see talk about Athlon64.  Is there a problem with installing on 
one and staying up to date?

Thanks
Bryan
