Transferring to a different domain

I’ve searched and cannot find a consistent answer so I’m turning to the forums for some help.

I’m working on transferring over https://daa.cirkut.net/ to https://www.daagolf.com

In the database, I’ve changed all the links (both the URI and wp_post stuff) to point to daagolf.com.

However, when all this is done, I CAN get to wp-admin, but when trying to log in, it keeps me at the login page. But if I go to the root (daagolf.com) it throws me into a redirect loop. if I leave both the uri’s at daa.cirkut.net, the site works as it needs to, and daagolf.com WILL take them to the page, but none of the links will point to daagolf.com

A little more information:
I’m using dreamhost.
Both sites are using the same database.
I have two folders with the wordpress core files (one for daa.cirkut.net and one for daagolf.com).

I’m at wits end and I really need to get this site to work for a client.

Any help at all will be appreciated. Thank you!
