We have Windows 10 systems already encrypted with BitLocker. I want to get them FIPS compliant. I know I have to set the security policy "System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing." Once that is set, what do I need to do to get these systems FIPS compliant? Do I need to decrypt and re-encrypt them or is there a method to get these systems compliant without having to go through decryption?
