The old requisition screen has been retired, but users can still access it through bookmarked links

Summary:

We have retired the classic requisition screen in production. RSSP is now the primary and only layout available to users. But some users who have bookmarked the classic page to their browser are still able to access the old/classic UI and use it. Is there a way we can remove it to its entirety? We would like all users to utilize RSSP.
