I need furl help - Can anyone answer a few questions?

I am on Invision Community v4.7.20 trying to convert one of my app to a new app (There is a converter for this from new app)

My old URL structure is like this

Old APP Index URL

mydomain.com/forum/oldapp/

Old APP Item URL

mydomain.com/forum/oldapp/view-12744-item-name-continues/

Old APP Category URL

mydomain.com/forum/oldapp/category/2-category-name/

New APP Structure

New APP Inder URL

mydomain.com/forum/newapp/

New APP Item URL

mydomain.com/forums/newapp/folder/433-item-name-continues/

New APP Category URL

mydomain.com/forums/newapp/category/6-category-name/

Question after converting my app to NEW one; How can redirect my old URL from Google or anywhere else to new URL structure?

I appreciate any help (Please help me write the code)

This will require a redirect on your server's end. You can ask your hosting provider for assistance.
