HI I think you can use the below query to check application scope

gr.addQuery('kb_knowledge_base.application',   'scope here');

Hi,

In the place of 2nd line have add. 

var nowDate = new GlideDate().getDisplayValue();
var gr = new GlideRecord('kb_knowledge');

gr.addQuery('kb_knowledge_base.application',   'scope here');
gr.addQuery('valid_to',  '<', nowDate);
gr.query();
while(gr.next()){
gr.setValue('active', false);
gr.update();
}

Is correct..?

I don't have much knowledge on scripting.

What is your specific scope? Basically knowledge articles are global so we can do query based on Knowledge base if each specific scope has a separate knowledge base or knowledgebase created on that scope

2 Knowledgebases is created on the scope. Can see in attachment.
