If you have more than one Uyuni installation, you will probably want to ensure that they stay aligned on content and permissions. Inter-Server Synchronization (ISS) allows you to connect two or more Uyuni Servers and keep them up-to-date.
To set up ISS, you need to define one Uyuni Server as a master, with the other as a slave. If conflicting configurations exist, the system will prioritize the master configuration.
For more information about ISS, see the Inter-Server Synchronization section of the Administration Guide.
