Changing the URL on Website.

Hello,

I have read and re-read the documentation on WP and Bluehost (my hosting) about how to change my primary domain on my website and the information is really vague to me.

So far I have:

1. Purchased the new domain (www.raincoastlotus.com)
2. Had Bluehost change which domain is my primary (now raincoastlotus.com) and parked (https://www.ojasathletica.com)

I know how to update the wordpress url & home, but doing that just makes it so I cannot login into wordpress anymore. Soo, I am definitely having to do some work in my database but without really detailed instructions I am not confident in working with my database.

Something I tried already and maybe just missed a step along the way:
1. I went to mysql created a new database
2. went to myphp
3. exported current database
4. selected new database
5. imported the previously exported database
6. went to my cPanel file manager
7. opened folder public_html
8. opened file wp-config.php and updated the database name and password.

It did not work and I panicked. Website was broken. SO I undid everything put everything the way it was and now I am here.

I think I am missing a step somewhere. But I don’t know what exactly it is or how to complete the step. Do I need to add this new database to my cpanel?

Thanks!
