My Mac running Snow Leopard has several MacPorts based open source software packages installed. Upon the upgrade to Lion, all my ports are listed as outdated.
It's safe to upgrade them en masse?

macports.org currently says: "Note for Lion users: There is no official release supporting Mac OS X 10.7 yet, but you can test the MacPorts 2.0.0 release candidate if you like."
I usually don't upgrade to a new major version of OS X until MacPorts has released their first official support for it.
I agree with Jerry Jacobs that you should probably back up your
/opthierarchy before attempting. Then you could try doingsudo port selfupdateto see if that upgrades you from 1.9.2 (or whatever) to the 2.0.0 release candidate. If it does, then you can trysudo upgrade outdated.I wouldn't try doing a
sudo upgrade outdatedon Lion without at least being on the 2.0.0 release candidate of MacPorts.
