 I went directly from 1.6.1_STABLE to 3.0_STABLE with no problems.  As the
other responder noted, run the "postinstall" script, it's awesome!  It
does take some time, like about 45 minutes for me to go through everything
i have modified, but it works very well.

 All i did was:

1) install 3.0 kernel

2) reboot

3) cd / ; tar zxf  each .tgz file

4) postinstall


 I had a bunch of pkgsrc to reinstall, too.

 I'm not sure about this, i don't use raidframe.
