I'm looking for a good reference to move from a single server (currently in production at 5.0.10) to a multiserver environment (5.0.10) as follows:

2 x LDAP
2 x Mail
2 x MTA

I already checked the "Multiple-Sever Installation" Document but it's geared towards a new install.

In essence I would like to do the following:

1. Create two ldap replicas and keep the existing master for later decommission.

2. Add two mail servers and point them to the ldap replicas

3. Add two mta's and have the mail servers use them.

4. Move accounts to new servers

5. Disable services on the original server

Thanks in advanced.
