More often than not, you can just go directly, however;

1. Remember backup first
2. Skim through /usr/src/UPDATING
3. Follow the procedure about updating everything, in the same file.=20

If possible, a fun option is to restore a backup to a spare machine (or VM) a=
nd upgrade the backup.=20

There's also ports to consider. I'll typically do a full ports rebuild after=
 jumping major versions. There's a similar /usr/ports/UPDATING.=20
