Upgrading from FreeBSD 5.4 to 6 - Make world or binary install?

[Jim Keller]

Hello,
    I'm trying to determine which version of FreeBSD to install on a new 
server I have coming in, since I know that the 5 branch is to become an 
errata branch sooner rather than later. The migration guide from 4.x to 
5.x recommends a clean install of FreeBSD followed by data restoration, 
which makes sense considering the major changes in 5.x, especially to 
the filesystem. However, will this still hold true for going from 5.x to 
6? I'd prefer to install 5.4 for now then run a buildworld later and 
bump it to 6, but will buildworld be a reasonable way of going from 5.4 
to 6?

Thanks
