This bug is created as a clone of upstream ticket:
Current replica creation model calls for creation of a package on the existing replica and then delivering it to the new replica host being installed. A more robust approach that would allow easier migration between different versions is to have the following model.
Install a client on a future replica machine.
Join in to the domain
Install server bits using yum install
Run a command to promote the client to replica. As result of this command the client would connect to the existing master and pull in the data it needs rather than having a replica package being manually pre-created and delivered.
The benefit is that the replica being installed would be able to get the data it needs in the format in needs. It would reduce the need to deal with the cases when the master is versions 2.x and the replica is version 3.1.x.
Until this is implemented it makes sense to defer the support of the mixed domains between the versions.
Might be a problem for Fedora though...
Replica Promotion and Topology features were postponed in the upstream project, to FreeIPA 4.3 which should closely follow FreeIPA 4.2 release.

Has been implemented upstream, see comments above.
