How to migrate from Apache2 to nginx in already installed ISPConfig 3

Hello guys, I have already installed ISPConfig 3 with apache2. I use varnish before apache2 but I want to switch apache with nginx+php-fpm. May I do that without losing any content and database?

 

That switch isn't possible. You'd have to set up the server with nginx from scratch.

 

Could you please let me know how ?

 

You can find tutorials for nginx here: http://www.ispconfig.org/ispconfig-3/documentation/
