 Default behavior changes
    * The PK, X.509, PKCS7 and TLS modules now always use the PSA subsystem
      to perform cryptographic operations, with a few exceptions documented
-     in docs/use-psa-crypto.md. This corresponds to the behavior of
-     Mbed TLS 3.x when MBEDTLS_USE_PSA_CRYPTO is enabled. In effect,
-     MBEDTLS_USE_PSA_CRYPTO is now always enabled.
+     in docs/architecture/psa-migration/psa-limitations.md. This
+     corresponds to the behavior of Mbed TLS 3.x when
+     MBEDTLS_USE_PSA_CRYPTO is enabled. In effect, MBEDTLS_USE_PSA_CRYPTO
+     is now always enabled.
    * psa_crypto_init() must be called before performing any cryptographic
      operation, including indirect requests such as parsing a key or
      certificate or starting a TLS handshake.
