### Upgrading

If you have an existing 5.x or 6.0 system and are running a generic kernel, the normal upgrade process, described below, will work.  

Change your local `/usr/src` to 6.4:

    cd /usr/src
    git fetch origin
    git branch DragonFly_RELEASE_6_4 origin/DragonFly_RELEASE_6_4
    git checkout DragonFly_RELEASE_6_4
    git pull

And then rebuild: (in `/usr/src`)

    make build-all
    make install-all
    
    (reboot your system)

    make initrd 

`make initrd` is optional for systems with unencrypted disks. 
 See the [initrd(7)](https://leaf.dragonflybsd.org/cgi/web-man?command=initrd&section=ANY) man page for details.

Don't forget to upgrade your existing packages.  6.4 packages have already been built and are immediately available.

    pkg update
    pkg upgrade

If you get a lua error when upgrading pkg, copy over a new config file:

    cp /usr/local/etc/pkg/repos/df-latest.conf.sample /usr/local/etc/pkg/repos/df-latest.conf
