Migrating an addon domain to primary domain

Hi, I'd like to migrate an existing addon domain that uses Wordpress to become a primary domain at a new web host.

I will be following these instructions here wpexplorer.com/migrating-wordpress-website/

In sum, I will have to:

1. Back up my site files
2. Export my database
3. Create the new database at the new host
4. Import the earlier database
5. Edit the wp-config.php file to include the database info created in Step 3
6. Upload my site files
7. Change the nameservers

Is that it? I somehow feel that I will need to make other changes regarding the directory paths or folders etc. because I will be transferring an addon to become a primary.

Also, my exisiting addon has free SSL (the one done with cPanel). Do I need to re-enable it or something? If yes, how can I do this?

For plugins, I use WP Super Cache. I do not use WordFence.

Thanks and regards.
