I've never done it myself, but I can't see any reason why not. Hardened is a |
| 23 |
strict subset of non-hardened (in terms of packages and versions) so it |
| 24 |
should just be a smooth, albeit long, upgrade. |

There may well be USE flags involved that introduce incompatibilities that |
| 27 |
can't be resolved, I wouldn't know about that. I would also suggest you find |
| 28 |
a decent howto written by someone who knows the process. You definitely want |
| 29 |
to get your USE, CFLAGS and CXXFLAGS right the first time. Otherwise you'll |
| 30 |
end up recompiling lots of stuff over and over, each time with new settings |
| 31 |
you forgot about the previous time :-) |
