I have two alb’s
alb1 – created by infra team manually to serve all the requests from asp.net MVC application
alb2 – created by Kubernetes automatically to serve all the pages from the next.js app
now I want to serve both the old and new pages(next.js) in a single domain.

something like this.

abc.com/oldpage - - serve from alb1
abc.com/* - serve from alb1
abc.com/newpage - serve from alb2

I tried few solutions like using the old alb in kubernetes to add more listener rules by path
but I am getting an error.
Can someone help what is the best approach to do something like this?
