Hi Simon

Without knowing specifically what you’re using and how you’re deploying, I mix and misuse aarch64 and amd64 daily.

In general ports and packages on both work just the same, with the caveat that any native code extensions to your languages (node, php, elixir) will require building on the correct architecture.

This being FreeBSD, that is not entirely true as there are tools like poudriere and other cross-compilers and emulators like army to do that.

So long as your package versions are in sync stuff should just work.

of course you can now deploy to arm64 servers too, I think all major cloud providers support this.

A+
