Greeting,
    I am planing a new IPA installation with potentially a large number of replica servers.  According to the documentation [1]:

Set up at least two replicas in each data center (not a hard requirement)
A data center can be, for example, a main office or a geographical location.
Set up a sufficient number of servers to serve your clients
One Identity Management (IdM) server can provide services to 2000 - 3000 clients. This assumes the clients query the servers multiple times a day, but not, for example, every minute. If you expect more frequent queries, plan for more servers.
Set up a sufficient number of Certificate Authority (CA) replicas
Only replicas with the CA role installed can replicate certificate data. If you use the IdM CA, ensure your environment has at least two CA replicas with certificate replication agreements between them.
Set up a maximum of 60 replicas in a single IdM domain
Red Hat supports environments with up to 60 replicas.
I have over 60 geographical locations I was hoping to place a replica.  I will easily exceed the 60 replica limitation outlined in the documentation.  Can any elaborate on the 60 replica limitation?  Is this a hard limit?  What are the contributing factors for the existing limitation?

Each location will have far less than 2000 clients.  Are there any considerations that could accommodate a larger number of replica servers? 

Thanks
