Have you noticed, there is all kinds of advise on the internet about the best way to move WordPress websites? There is literally a myriad of ways to achieve this. One of the methods I read on
Changing Your Domain Name and URLs
Moving a website and changing your domain name or URLs (i.e. from http://example.com/site to http://example.com, or http://example.com to http://example.net) requires the following steps - in sequence.
Download your existing site files.
Export your database - go in to MySQL and export the database.
Move the backed up files and database into a new folder - somewhere safe - this is your site backup.
Log in to the site you want to move and go to Settings > General, then change the URLs. (ie from http://example.com/ to http://example.net ) - save the settings and expect to see a 404 page.
Download your site files again.
Export the database again.
Edit wp-config.php with the new server's MySQL database name, user and password.
Upload the files.
Import the database on the new server.
I mean this is truly horrifying steps to take, and I don’t see the point at all. This is how I achieved it for one my customers.
1. Take customer Database Dump
2. Edit the database searching for 'siteurl' with vi
And just swap out the values, confirming after editing the file;
[root@box]# cat somemysqldump.sql | grep siteurl -A 2
(1, 'siteurl', 'https://www.newsiteurl.com', 'yes'),
(2, 'home', 'https://www.newsiteurl.com', 'yes'),
(3, 'blogname', 'My website name', 'yes'),

There might be additional bits but this is certainly enough for them to access the wp-admin panel. If you have problems add this line to the wp-config.php file;
Just before the line which says
/* That’s all, stop editing! Happy blogging. */
And then just do the import/restore as normal;
mysql -u newmysqluser -p newdatabase_to_import_to < old_database.sql
Simples! I really have no idea why it is made to be so complicated on other hosting sites or platforms.
