Part of the site on WordPress, and part on Yii - on the same domain - how?

Question

Yii

We have a site with a lot of content, it runs on a homemade CMS built on the basis of Yii 1.x
Slowly but surely we create a new site on WordPress - everything is going well, but not as fast as we would like.

The authorities want some sections of the site to already start working in a new design from under WordPress
. At the same time, it is still impossible to switch the entire site to WordPress - not all sections of the site and content are implemented there (2-3 more months of work)

Is it possible to implement the work of some sections site on WordPress - at the same time, so that other sections would not fall out and would also be available on Yii as before - and all this on one domain?

Answer 1

Finish it, then post it. WP can live in a separate directory, but in the end it will have a bad effect on SEO.
