Profile Manager and Open Directory Replicas

[-Tim]

I am about to migrate from Workgroup Manager to Profile Manager and I wanted to see if anyone is currently using Profile Manager with an Open Directory replica. Our current OD server does not have a replica but we are going to replace it with two Mac Mini servers. I have not set up a replica before and I want to know if it provides redundancy and load balancing for Profile Manager and Workgroup Manager. Everything I am reading mentions about how it replicates OD. Does it also replicate WGM and PM settings/profiles or does it only replicate only users, groups, user groups, and computer groups and the account settings?
