Postgres storage migration

We are using openshift environment and postgres version 15.2. We want to change storage from ceph to local storage. So, Storage team made default storage as local. Now, I created a new cluster with same postgres version and I am planning to take backup from old cluster to new cluster. Size is 100gb. Ram 24gb, cpu 2.

My question is, is there a combination of pg_dump and pg_restore that takes less time to complete the task?

Last time it took more than 8hours. We were taking schema only dump using dumpall . Then data only backup using pg_dump in directory format.
