Moved WordPress site to new URL but isn't working

Hi friends.

I’ve transferred several websites before yet this one is giving me a bit of trouble. I imagine it is because I was not the one who built it and there is something I am missing.

Original URL: https://www.gloryofthelamb.com

New URL: behold-ministires.org

My workflow:

I created an addon-domain for behold-ministries;

Copied the files over from GOTL > BM;

Changed the URL in MYSQL siteurl to behold-ministries.org;

Changed the DNS to current host.

Now, raw text and the logo appear, but a few critical issues are occurring:

1) Web links are ending in .com instead of .org;

2) The theme stylesheets are not being displayed, even though the contents folder has been copied.

3) Log-ins are being prohibited because my browser ‘does not allow cookies’ but this is erroneous because I’m working on several WP sites right now which are allowing me entrance.

Any thoughts here?

Thank you!
