What is the impact of changing a primary .edu to a subdomain .edu?

[msmcsearch]

Hello

I'm looking for feedback on the impact of search rankings, overall SEO efforts and how Google will view changing example.edu to subdomain.example.edu

All URLs/content under www.example.edu and example.edu would be 301 redirected to subdomain.example.edu, essentially making subdomain.example.edu the primary domain.

Thank you!!

301 redirects don't pass all their link juice, so you may see a slight rankings drop, but otherwise Google should treat the site the same.

Universities are really bad about changing the URLs of their homepage, department pages and other important content.   Most of the time they do it for no good reason or even bad reasons.

Why would you want to stink up the URL of your homepage?
