Answer 1

i did some reserches and i foud that i have to update the DoctrineMigrations config file config/packages/doctrine_migrations.yaml :

from

doctrine_migrations:
    dir_name: '%kernel.project_dir%/src/Migrations'
    # namespace is arbitrary but should be different from App\Migrations
    # as migrations classes should NOT be autoloaded
    namespace: DoctrineMigrations

to

doctrine_migrations:
  migrations_paths:
    "App\\Migrations": "src/Migrations"
