Good because you have access to newer features of the server as well updated software (such as perl and python).
Bad when some things break.
For Rankk, the PM, forum and some challenges broke because they used an encryption module that ran into some issues with the new architecture. A few challenges that use PHP (e.g. Invisible captcha) broke because the new PHP is version 7 and our PHP 5 code broke. The PHP MySQL functions mysql_query and mysql_connect crashed and needed to be replaced with mysqli_query and mysqli_connect. How globals worked between PHP 5 and 7 seem to have changed too, so some recoding was involved.
Fortunately things weren't that bad and only a few things needed fixing.
