Is SEO affected when changing from siteA.example.edu to siteB.example.edu/siteA?

[AnneHolz]

Are there SEO ramifications as a result of moving a group of sites that currently each have their own subdomain, under one subdomain?

Ex: changing college.example.edu, dept1.example.edu and dept2.example.edu  to college.example.edu, college.example.edu/dept1  and college.example.edu/dept2... etc.

For example, let's say dept2 has a page about 4H and dept3 has a different page about 4H, if they're no longer their own subdomains, could only one of the 4H pages rank?  In addition, would moving the department name further down the URL path cause the department's front page not rank as well?

Thanks,

Based on what I understand to be your question, no, just make sure that you have 301 redirects in place. I'd question the need to still use subdomains though
