### Transition to NGINX

1. Initial testing strategy is to move NGINX to port 80, and proxy everything to Apache on port 8090 -- creating a shim.

2. Without PHP available via FastCGI, any function at all for PHP-based applications validates NGINX.

3. Current state (2020-01-12).

   1. Principal functions migrated to NGINX
      * Admin Console
      * kalite -- goes directly to port 8009
