I am having my Openldap server acting as master/slave in RHEL 3 its in 32 bit architecture.It acts as primary authentication for all my services.I need to enhance my servers with new version of OS which will be in high availability. I preferred to go for RHEL 5 in 64 bit architecture.

I need to know if i configure Slave LDAP server in my new setup i.e in RHEL 5, whether i can able get all the users informations which is stored in my old setup through Master/Slave communication without any downtime.
