I want to upgrade to php 5 on one of my servers, but I still have a drupal install with 4.7 (yeah, yeah it should be upgraded but I can't do that now).

Does anybody know if once I upgrade to php5, will this cause any issues with my drupal 4.7 install?

AFAIK Drupal 4.7 is compatible with PHP 5. 4.6 or 4.5 and lower weren't.

I am sure there are a lot of sites still running 4.x in PHP 5 hosts
