It isn't supported. No work has been done in trying to mkae it possible.

Sounds like there are some packages installed from the new distro/arch.

I guess you meant _not_. What ? no boot or swap ?
Make a back of /home data to another disk or system. It makes it a lot 
easier to mess with this stuff, and not lose info.
Once that is done, if you do have swap, it might be big enough to change 
to ext3fs to hold the contents of you /home dir. Move the data there, 
then you can do a fresh install overwriting your old / with  /boot / 
/home. Or maybe swap is big enough to hold a minimal system install that 
you can use to resize partitions {or do it from the rescue CD}.
gparted gui makes expanding or moving ext2/3fs easy, but I don't think 
it can reduce the size of it.

rpm -qa --qf="%{name} ">rpms-installed.txt
This makes one long line of space separated package names. You might 
need to separate them into blocks that aren't too big for the yum 
command line to have trouble with.
