In need of deactivating a trigger in Production? Haven't found a way to do it?
I don't know if people are aware of this, but I've seen numerous posts about it, I've suffered from it myself and even had support tell me it's not possible.

So I was a bit surprised when today, playing around in Eclipse, I successfully managed to deactivate and activate a trigger in Production!
What you need to do is to open the metadata file accompanying the trigger. So, if your trigger is Foo.trigger, you would have a Foo.trigger-meta.xml.
Open that one, change the value of the element <active> to "false" and save the file.
Once saved, doublecheck through the GUI and the checkbox for Active is no longer there!
Sweet!
Of course, to re-activate the trigger, just change the <active> element to "true" again.

Hope this helps someone.
