I find this very annoying and time-consuming: http://www.zabbix.com/forum/showthread.php?t=10701&highlight=duplicate+triggers
Importing a huge template with a lot of hosts creates duplicate triggers. This happens when only the expression of the trigger was changed and the template is reimported. As I understand from the thread the default behaviour in 1.4 was to update the trigger expression in the existing trigger. In 1.6 this was changed and the old trigger is not affected, instead a new trigger with the same name is created. Either I have to delete all old triggers then or completely delete all template linkages and link all hosts to the new templates afterwards. This takes a lot of time...
Is it possible to create a switch/an option where this behaviour can be configured to the 1.4 behaviour?
