Cakephp and Laravel coexisting

Question

I do receive a chalenging task to migrate a old legacy cakephp 2 app to laravel 5.2.

The two must coexist and work togheter, while all modules are migrated to laravel because it is a large app.

Is it possible/feasible? the auth session credentials can be transported to laravel auth session easily?

What kind of traps you can find int this proccess? and how can i avoid them?

I have only found these steps : http://laravel.io/forum/09-08-2014-strategy-for-migrating-a-large-cakephp-project-to-laravel?page=1#reply-28620

Anyone already done this before ?.

Answer 1

The by far most logical solution would be to transfer the entire application over to Laravel at once. However, if that's not a possibility, it should still be possible. If you keep sessions in Redis, they'll of course be accessible by both applications. The main issues might be:

1. You want a User object on the Laravel app to authenticate, but authentication happens in the Cake app. Hence, you might need to reauthorise somehow in the Laravel application. However, if you know the session is valid and you have the user ID, you can do this without issue.
2. The session token is generated differently: Laravel will generate its token through one algorithm, using its application key. Without any knowledge of CakePHP, I'm confident the session key is generated differently. You might be able to surpass this by modifying the generation of the key for them to match. Otherwise, you'll end up with issues for hashing salts, CSRF verification and whatnot if those things go between the applications.
