Is safe change to Nginx. Jose like only Nginx, its good configured.
All sites remain there, only you can't ad a new site when uninstalled all 3 (OLS, Nginx, Apache).
When ad one of this, you can again ad a new site.
When uninstall the port 80 and 443 not work, but Nginx can install in 1 minute approx and all ports working again.
My Question: when OLS can handle 52 sites, why you want change?
