Clarification needed on deletion/archiving of open question threads

I read Michael Schwandtu2019s "Next steps on improving quality" [blog |https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/10171] [original link is broken] [original link is broken] [original link is broken];which states that old unanswered threads will be deleted/archived.

As an immediate step we have limited the number of open = unanswered threads
to 10 per member. Beyond that we plan to delete / archive all open questions older 
than 6 months up from late summer. So please go into your control panel in the
 forums and either 1) close your question(s) and provide the points (if it makes sense)
 or detail your question or simply do nothing and wait for us to delete all open question.

I hope that threads with at least one response are not permanently deleted even if they remain unanswered. Many of these types of unanswered threads have good suggestions or the actual answer. Some of the original questions posted may be by people who no longer visit SDN and wont be able to close their questions.

What will happen to such types of threads? Will they permanently be removed or archived somewhere else and still be available for consulting? Thanks.
