A company is deploying a new file server to consolidate shares from several legacy servers. Which of the following is the BEST method to ensure that the new file shares are being used?

Shutting down legacy servers without remapping shares would lead to users losing access to critical files and cause significant disruption to operations.

Removing DNS entries for legacy servers would prevent name resolution but would not automatically remap existing drive letters or ensure users connect to the new shares.

A logon script can be deployed through Group Policy or other centralized management tools to automatically disconnect old network drives and remap them to the new file server's shares upon user login. This method ensures a consistent transition for all users, minimizes manual intervention, and significantly reduces downtime or confusion by automating the update of drive mappings.

Manually visiting each user's computer to modify drive mappings is an extremely time-consuming and inefficient method for a company-wide migration and is not scalable.
