Just thought I'd give my $0.02 -- I've never tried the sym. link approach
and don't know what would be needed to make it work.

Personally when I need to run two versions (or transition from one to
another), I just make a complete copy of everything.  Then I use Apache
DocumentRoot and VirtualHost directives to control which one is the
http://www.example.org/horde/ and which has to specify a port number in
the URL.  Then I can roll what the users see forward and backward with
just Apache directives, and have access to the other one simultaneously
for myself.

    /var/www/html/horde
                       /imp
                       /turba
    /var/www/html223/horde
                          /imp
                          /turba

If you have GNU cp, using "cp -al" would make a copy where it uses hard
links, thus removing the waste.  But really, with modern machines, these
little PHP scripts are very lightweight.  I don't lose sleep over two or
more completely separate copies.

In my experience, I don't run with two parallel versions for very long;
it's usually a transitional step, and the old one goes away pretty
quickly.
