It looks like pulp restricts to run multiple migration plan at the same time. https://pulp.plan.io/issues/6639

But katello is triggering API to run all the migration plan at once. https://github.com/Katello/katello/blob/64f9d6a7dfcf4347ec8937ecf42642adfbed8512/app/services/katello/pulp3/migration.rb#L46
