Laravel项目在另一个laravel项目中

I have project which is built with laravel 3.

Currently, I made another products using Laravel 5.2.

Is it possible to have Laravel 5.2 within Laravel 3. HOST do not care what framework is used.

In this case we have two ROUTES.

Both uses same DB.

It would be real nice if we could do this:

http://aaaa.com/ is the main application which is redirected to public_html

and is it possible to do this:

http://aaaa.com/laravel5/ is the application in Laravel 5.2 redirect to public.

What do I have to do in .htaccess?

any help would be nice
