Duplicate Windows Cluster class [cmdb_ci_windows_cluster] with Extended CMDB "com.snc.extended_cmdb" PluginDetailsThe cmdb_ci_windows_cluster table is basically obsolete, and there is no out-of-box code in the current versions that would use it for anything. This is present because at some point in the past, you will have installed the now-legacy Extended CMDB plugin.All Discovery, Service Mapping, Suggested relationships etc. only use the cmdb_ci_win_cluster table now.cmdb_ci_windows_cluster can be ignored. To avoid using the wrong one, the label could be updated.The Module could be deactivated to hide it in the navigation: Out-of-box it's /sys_app_module.do?sys_id=9eb35e494a36231401b4cf285ba283f3Actually deleting the table would be problematic, and we don't recommend you to delete the table.
