Hi Mridula (and greetings of the season to you again urmas),
Try configuring your own set of two or three New UX blueprints, and then assign (drag-n-drop) Classic PPM project templates to each one. From the bottom-up in the image below, your projects will subscribe to their parent template, which in turn, subscribes to its parent blueprint.
You can also assign access rights (individually or by groups) and users can "get on the same page" by using the same shared saved view of various pages (best experienced in CA PPM 15.5.1).
Definitely start here: New User Experience: Configure Project Blueprints.
Hope this helps! You are on your way!
Kind Regards,
Damon
