Hello User404404,   At this time there is not support for other instances. There is a feature being planned in the future to allow for this​, sort of a master instance of OME for other OME instances to roll up to.  
Hello team !Due to our facility security policy, i have to create a secondary appliance of my OME entreprise running on VmW7.03As i created lot of custom group / baseline / script / mailing list alerts... i can't manage those future two instance separately.At first, I thinked to create a VIP and write an incremental copy of both each night, but it's seems very difficult and hazardous.So, Is there a possibility to link instances as "primary" - "secondary" with inherited dependances ?Or maybe some other tricks to do the same ? Thanks for your help !
