/crx/packmgr/update.jsp not found
Hello everyone,
I'm using AEM 6.4 and want to update a package I created (add some filters to the package) with a curl command.
unfortunately, when I try to send a request to http://localhost:4502/crx/packmgr/update.jsp , I get a 404 Response.

"/crx/packmgr/service.jsp" and "/crx/packmgr/list.jsp" both are working fine. It's just the update.jsp that is missing.
On the production server, the update.jsp file is available.
Where can I find the update.jsp file to transfer it from the production server to my local instance?
Thanks a lot
