They offer CentOS and Fedora on their virtual machines. I use Fedora
on my home machine, but switched to CentOS on
the virtual machine because it's a hassle to frequently upgrade, and going from
fedora 16 to 18 was impossible
without reprovisioning the machine.
because you can't skip a version
i maintain around 20 production servers over years running with
fedora and *all of them* where upgraded from F9 to F18 with
yum as well the upgrade to F19 is tested and easy
you only need to follow the instructions and in case of GRUB2
it is also easy and painless to move /boot in case you have a
own virtual disk for it to get the needed free space
hence you can even do this on one virtual machine and blow
the dd-image including the partition table to the other
machines if they are maintained well and have the same software
based from the same golden master
so no - it is *not* impossible
