How are we supposed to migrate from #pragma simd?

If I try

double* ptr1;
double* ptr2;
__assume_aligned(ptr1, 64);
__assume_aligned(ptr2, 64);
#pragma simd
for (int i=0; i<n; ++i)
   ptr1[i] = ptr2[i];

it will vectorise the loop with aligned access, but gives a warning that #pragma simd is deprecated.

If I swap "simd" for "vector aligned", it does not vectorise and  the optimisation report says "use the simd directive".

The documentation for #pragma simd (https://software.intel.com/en-us/cpp-compiler-developer-guide-and-reference-simd) doesn't mention deprecation or any alternatives.

Is there any documentation/articles that tells us how we are supposed to do this these days?
