Can I move sites already created?

If I have websites already installed on a multisite install of wordpress. Is it possible to move them to another domain with a multisite install.

My website has a dedicated IP address and currently I have websites on the multisite install of it (through subdomains). I've recently changed a bunch of things on the site and I want to move those websites onto a different subdomain with directories.

So for example the site examplea.mysite.com already exists. I want to move it to, sites.mysite.com/examplea.

Is that possible? If so how would I do it? And would multi domain mapping plugin come into play somehow?

Thanks so much!
