I've just updated my main server to 3.3 lastest snapshot this afternoon. Until now no problems at all, but... well, now I have to update >30 packages.
Do I really need to pkg_delete, pkg_add every single port, or are there better ways to accomplish this?
No, there is no "nice" way to do it at this point, so you really need to do that (but you can write a script or something to ease the process).
no need to, use 'openbechede upgrade' ;)
