Are there any issues running PHP 5.6-based code on a PHP 7.x VM?

  Very few. It's worth running one of the code analysers over your codebase to check: https://github.com/PHPCompatibility/PHPCompatibility https://github.com/PHPCompatibility/PHPCompatibility I upgraded a large project last month, and this found 6 changes I had to make in 20k LOC.

  Depends on the x, but more importantly, depends on the code.

  With clean code it’s probably ok. But with other “clever” code you may see different behavior which is often hard to catch.
