Incorporating subdomain into root domain

Hello everybody

I want to move my blog from blog.domain.com to domain.com. Currently, the subdomain and the root domain are hosted as two different webflow projects. This is because our blog is a bit complex, but it now makes more sense to host it under the root domain. I want to basically take all the content from the subdomain and incorporating it in the main project.

Is it enough to remove the subdomain from one project and adding it as a custom domain to the main project? The url structure will be the same, i am transferring all the content to the main project. Ex. blog.domain.com/blog/article will just be domain.com/blog/article

Should I worry about duplicate content issues/ set up redirects?

Thank you in advance!

Yeah you can export it and put it to your own server. You can take a look at my account, posted several videos about it.
