When Windows Server 2012 support ends, it is crucial to plan and execute a migration strategy to maintain security and support for your server infrastructure. Start by assessing your current environment and identifying the applications and dependencies. Choose a suitable target operating system, such as Windows Server 2016 or 2019, and develop a comprehensive migration plan. Backup and migrate your data, test application compatibility, set up the new server environment, and migrate services and applications. Validate and test the new environment, communicate with users, and provide necessary training. Finally, decommission the old server. Involving IT professionals can ensure a smooth transition and address any challenges that may arise during the migration process.
