migrated repo: Migrated/Total repositories: 686/693 , is there a way to find the not migrated repo and possbile recreate these ?

How did you get to katello 4.0? You have to migrate the content to pulp3 before you update to katello 4.0. It’s not part of katello 4.0 anymore.

See Foreman :: Plugin Manuals on “Pulp3 Migration”.

I did content migration when upgrade from katello 3.17 to 3.18 , but after upgrade to 4.0 , I checked it again , it still showed Migrated/Total repositories: 686/693.

Now that you are on Katello 4 it doesn‘t matter. You are migrated and pulp2 doesn‘t work anymore.
