Windows 11 is designed to support most applications that ran on Windows 10, but challenges may arise due to undocumented legacy applications and configurations. A thorough evaluation of devices, including installed applications and data locations, is essential to minimize disruptions during the upgrade.
Migrations can be categorized as clean installations or in-place upgrades. A clean installation erases the previous OS and data, while an in-place upgrade retains existing settings and applications. In-place upgrades are not allowed for certain transitions, such as from Windows 10 Home to Windows 11 Pro without first upgrading to Windows 10 Pro. IT professionals often prefer clean installations to avoid carrying over issues from the previous OS.
During an in-place upgrade, data in library folders is retained, but data in the Windows folder may be at risk. Compatibility issues may arise with poorly designed applications or drivers post-upgrade, particularly with legacy applications reliant on outdated frameworks.
Preparation for migration includes creating an inventory of applications, identifying potential incompatibilities, and ensuring backups of data. IT must also confirm hardware meets Windows 11 requirements. If a clean installation is chosen, strategies for application installation must be developed, utilizing tools like System Center Configuration Manager or Microsoft Intune.
Validation and testing of migration tools should occur in a lab environment, followed by a pilot deployment on a small percentage of machines. After successful pilot testing, the final deployment can proceed, followed by an audit to address any issues. Careful planning and testing are crucial for a smooth migration process.
Support for Windows 10 Enterprise LTSB 2016 and Windows 10 IoT Enterprise 2016 LTSB will end on October 13, 2026, while Windows Server 2016 will reach its end of support on January 12, 2027.
