Hello,
Thank you for posting in Q&A forum.
Domain cloning refers to the process of creating a new domain similar to the original domain during computer and user migration. This process typically involves copying existing domain settings, user accounts, group policies, etc. to a new domain in order to preserve the original domain configuration and user information in the new environment.
