they can happily coexist one next to the other.
I did that on a couple of machines as follows:
- dowloaded python 2.3.3 and installed it
- created a new user zope27  (mandatory but usefull)
- created a directory /home/zope27/instances
- created ~/Products
    unpacked CMFPlone-2.0-final to this directory
    created a softlink CMFPlone-2 pointing to CMFPlone-2.0-final
- dowloaded Zope and unpacked it to /home/zope27/Zope-2.7-0-src
- installed zope to reside in /home/zope27/Zope-2.7-0 with
   configure --prefix=~/Zope-2.7-0
- created instances of zope with ~/Zope-2.7-0/bin/mkzopeinstance in the 
~/instances
- edited ~/instances/INSTANCEX/etc/zope.conf to my liking (at least 
port-base so it does not run at the same port as the 2.6.2 version)
- copied OLDZOPE/var/Data.fs do ~/instances/INSTANCEX/var
- made softlinks in ~/instances/INSTANCEX/Products pointing to all 
directories in ~/Products/CMFPlone-2
- started the new zope with ~/instances/INSTANCEX/bin/zctrl start
