User/Roles, Owner, and privileges migration strategy

Can you please let us know what is the best strategy or different approaches to migrate users/roles, privileges and owner to different PaaS PostgreSQL instance like AWS RDS or GCP cloud SQL from on-premises? There are different use cases and how this can be handled like “Alter Owner” of an object runs first before grant all privileges in pg_dump and it fails in the PaaS services.

Thanks & Regards,

Aditya
