upgrade from 6.1-RELEASE to 6.3-RELEASE

[Roberto Nunnari]

Hello list.

I'm about to upgrade from 6.1-RELEASE to 6.3-RELEASE
from source and I'd like to ask a couple of questions.

1) Do the system interface change? That is, will I have to
recompile all ports after upgrading?

2) Any gotcha, hints or things to be aware of?

Of course, as usual I'll take full backups before beginning
the upgrade..

Best regards.
