That would probably be the best.  The data format hasn't changed (you're 
not going from 32bit to 64bit, are you?).  You should just be able to 
install the software on the new machine, then run setup, then shutdown 
all of your servers.  Make backups of /opt/fedora-ds/admin-serv and 
/opt/fedora-ds/slapd-* and /opt/fedora-ds/shared/config just in case. 
Then, just copy over /opt/fedora-ds/admin-serv, /opt/fedora-ds/slapd-*, 
/opt/fedora-ds/shared/config, and the config directories under 
/opt/fedora-ds/clients.
