I like to keep the existing version running, while I test/setup new version, then swap when I'm happy everything is running ok.

Then told the installer to use the relevant /boot to install the bootloader. However that sort of broke from F18 and I've had to use the workaround in bug 872826 to get that to work. Can I just use grub2 ? to manage booting, I guess one version of F20 will have to be the owner. How will updates work, can they both update the grub2 config when the kernel is updated ? I've googled around and not really found any simple solutions. This artificial looks possible, but seem to require some manual fiddling around https:// www.happyassassin.net/2014/01/08/how-to-do-manual-multi-boot- configuration-with-fedora/ I don't think its too much of a mad idea to want to do a staged upgrade to next version, and I quite like have a clean install to get rid of all the stuff I've installed just to play with. - Any suggestions, or link's I haven't found.

Not automatically.
p1 boot1 ( F19)
p2 boot2 ( F20)
What you end up with in this case, is broken F19 right now because in
the F20 install environment, the F19 / LV isn't activated. So
grub2-mkconfig won't find F19 and thus won't make a boot entry for it.
If you boot F20, activate all the LVs, and re-run grub2-mkconfig -o
/boot/grub2/grub.cfg then you'll get a grub menu that has both Fedora
20 and 19 boot entries.
However, the F19 boot entries are a.) generic, they do not contain any
Fedora 19 specific boot parameters; b.) it's not updated from within
Fedora 19 when you get kernel updates.
So this is sort of brain dead simple for upstream grub folks to fix,
but they just don't give a crap near as I can tell. Or maybe they
think it's so brain dead simple that users should do this, or the
distributions should make grub work this way - I don't know. UX is not
GRUB's forte.
What you can do instead is, on Fedora 20, modify /etc/default/grub,
adding a line to disable os-prober:
GRUB_DISABLE_OS_PROBER=true
That will prevent it from using os-prober to generate the Fedora 19 entries.
Then you'll use /etc/grub.d/40_custom to add your own boot menu entry,
which will forward to the Fedora 19 grub.cfg using something like
this:
menuentry 'Fedora 19' {
set root='hd0,msdos1' ## I'm assuming your F19 grub root is the first
/boot partition
search --no-floppy --fs-uuid --set=root uuidforF19boot ## You can
can this fs volume UUID from blkid and just copy/paste it in, this is
optional but more reliable if you have more than one drive attached
configfile /boot/grub2/grub.cfg
}
Save that and rerun grub2-mkconfig -o /boot/grub2/grub.cfg
So what this does is it makes the Fedora 20 grub.cfg contain a single
menu entry for Fedora 19. If you choose that Fedora 19 menu entry you
will get a new GRUB menu that contains only Fedora 19 boot entries.
Since you're now directly using the Fedora 19 grub.cfg that's updated
by grubby when new kernels are installed, you'll always have an up to
date grub menu for F20 and F19 once you've done all this work.

I always use a stand alone grub2 that boots from the MBR and has configfile entries to boot the different fedora versions I have installed in separate partitions with everything installed in / (/boot, /home, etc. as a ordinary subdirectories).
