[389-users] Question about installing on new servers

We have 2 new servers that we are bringing into our suite, and we'd like 
them to eventually take over the current 389-ds role.  We currently have 2 
servers that are running 1.2.1 on CentOS 5.7 64-bit, and the 2 new servers 
are being installed with RHEL 6.3 64-bit.  What we'd ultimately like to 
see/have happen is:

install 389-ds on the new servers
set up replication to replicate the data from the 2 old servers to the 2 
new servers
point the underlying LDAP operations to the 2 new servers
take the 2 old servers out of the mix

Does anyone have any ideas or thoughts on if this is a good plan?  And the 
best way to accomplish what we'd like to do?

Thanks,
