Moving groups of threads by age
 

I want to move a large number of threads* by age [meaning* in this case* oldest to newer]* into a sort of archival collection accessible only be premium users.

How can I do that? I was thinking it would be easy* and have looked at the move threads feature* but I am somewhat confused. Can I choose age options and also a source forum option and have all that work together?

I am thinking I have moved threads in large groups before* but the control panel does not seem familiar enough to remember how it works.

thank you
