Is there any way to move user made custom alerts between CAS servers which ones are managed by own rum Consoles? I found this Product Idea, but is the status still that we can't move alerts between CAS servers (versions 12.3/12.4/2017)
at this time there's no tool dedicated for alerts export/import. One may try to copy "CAS\config\alarm-custom.xml" file to another CAS instance, but both report servers should be in the same version. I can only encourage you to vote for the linked Product Idea.
