secure boot migration

Secure boot migration refers to the process of updating or replacing Secure Boot certificates and boot components on Windows systems, often as part of servicing or security hardening. On WindowsForum.com, discussions cover real-world impacts such as BitLocker recovery key prompts after updates like KB5087420, and vulnerabilities like the BitUnlocker attack that exploits outdated boot components. Key themes include enterprise management challenges, the balance between security updates and operational risk, and the importance of maintaining a current boot trust chain to prevent downgrade attacks. The tag is relevant for IT administrators and advanced users dealing with Windows 11 23H2, TPM, and BitLocker configurations.
