The user is looking to run multiple Eyeglass appliances
Although it can be done, It is not recommended to run multiple instances of Eyeglass. Each instance of Eyeglass will require it’s own licenses. One Eyeglass appliance is capable of handling multiple clusters.
Conflicting Eyeglass instances can report the error when multiple appliances are applying those settings.
For example, if two instances of Eyeglass were running and trying to create a replication on a destination: one instance would create the replication and the other would throw an error because the replication has already begun.
