We have an production VM server with Windows 2012 R2, Coldfusion 11, PHP 7, mySQL 5.5 and SmarterMail with about 30 sites on it.
Our hosting company is recommending we move to a new VM with new versions of all installed and migrate our sites our to the new platform.
We do plan to do this at some point, but in the interim, would it wise or just inviting trouble to upgrade our existing Windows Server 2012 to Server 2016?
Our reason is that we are being often hit with SYN attacks, and have been advised Windows 2016 will be better at mitigating the SYN attacks.
If we did, would we have to reinstall CF, PHP, mySQL, SM? Or would the upgrade process keep all the current 2012 configuration settings and migrate them to 2016 version?
Or are the 2012/2016 versions too different and its bound to cause problems?
thank you for any help, Alex
