Approximately this sequence.
It may differ depending on the system on your old hosting, depending on the site itself, its CMS, the database is used or not, etc.

1. If this is the first (main) domain on our hosting, then it has already been added to the system, and you do not need to add it additionally. All files for the main domain are uploaded to the /public_html/ folder on the server.
   If you want to make and transfer an additional site to us, then add the domain you want to transfer to your cPanel account on our hosting as an Additional Domain.

2. Download all the files from the old hosting (it is convenient if you can archive all the files of the site through the file manager there and download one file).


3. Download the database from the old hosting (if the old site used it)
   This is done either in the "Backup" section or via phpMyAdmin in the old control panel.
   (done as an Export. The result is a text file with the database, the .sql extension, or an archive with this file.)


4. Upload the archive of files to the appropriate folder for the new domain on our server. (/public_html/ if this is your main domain, or to a newly created folder that was created when adding an Additional Domain)
   Unzip the archive through the file manager.

5. If the old site used a database
   Visit our cPanel, create a new database And a database user (with a password)

6. Visit our cPanel in phpMyAdmin and there you do
   import of the .sql file that you exported earlier on the old hosting.


7. In the settings of the migrated file, usually in the configuration file, for example "wp-config.php "
   specify the database name, the database user, and the password that you created in paragraph #5


8. On the domain registrar, change the DNS settings, and direct your domain to our DNS
   ns1.s0avahost.net
   ns2.s0avahost.net

That's it, the site has been moved and in a couple of hours it should completely move to our server.
