Hello, I am trying to move thousands of threads to archive. We have threads going back to 1999 and the forum list is slow to load. I have tried doing this 2 ways, via move topics [does not seem to work] and by selecting all the threads on a given page and moving them 60 at a time. The latter is very time consuming. When I try to move thousands via the "move topics" feature, nothing seems to happen. It will spin for hours and hours and end up moving nothing.

Can someone help? Thanks
