as I understand it (and I have been doing new installs with Ubuntu and not CentOS 6), CentOS 6 uses the dynamic config methodology thereby rendering slapd.conf and the previous methods for configuring ldap useless & down the self-defeating path.
The way to 'migrate' isn't that complicated - you need to do a slapcat of your previous (CentOS 5) openldap server into a file. Then you need to set up the base configuration and database via the dynamic configuration methodology.
I can point you to the methodology for Ubuntu - https://help.ubuntu.com/10.04/serverguide/openldap-server.html and the process on CentOS would almost be the same with the exceptions being the software packages have different names on CentOS and the configuration data would be in /etc/openldap on CentOS and in /etc/ldap in Ubuntu.
I suspect that someone has documented a similar guide for CentOS but I don't know where.
