What action should be taken with the FSMO roles during an upgrade process?

Transferring the Flexible Single Master Operations (FSMO) roles to new domain controllers during an upgrade process is essential for maintaining the integrity and functionality of the Active Directory environment. The FSMO roles are crucial for various operations within the domain, such as managing directory information and ensuring the correct functioning of the domain infrastructure.

By transferring these roles to new domain controllers before an upgrade, you significantly reduce the risk of service interruptions. This practice ensures that the new servers will take over the responsibilities of the FSMO roles without issues, allowing for a smoother transition and minimizing the chance of downtime or complications that may arise if roles remained on older hardware or software configurations.

This approach also helps maintain continuity and reliability of the environment by placing FSMO roles on servers that are being prepared and optimized for current workloads and functionality. Keeping FSMO roles on existing servers may lead to potential risks or challenges, especially if those servers are becoming outdated with the new upgrade process.
