How to make a blog and portfolio with different Wordpress themes on the same site?

Question

Blogs

I understand that the question may seem trivial. Googled the answer, didn't find it. Therefore I ask.
There is a site that was originally conceived as a blog, it is on WordPress, everything is already working. Now there is a need to place a portfolio on the site. I want to make a main page that leads to a blog and a portfolio. But how to file a portfolio section, again on WordPress, but with a different theme? How to differentiate one CMS for two tasks?

Answer 1

wordpress multisite
