Migrating WordPress to a new server, how to move your site without downtime or data loss
In short: migrating WordPress to a new server means moving the files and database to the new host, testing the site on a temporary address, and only then switching the domain. That order means visitors see a working site the whole time, while you avoid downtime and data loss.
There are many reasons to change servers: slow hosting, frequent outages, a growing shop that outgrew its plan, or simply a better offer elsewhere. The good news is that WordPress can be moved calmly and practically without interruption, as long as you do it in the right order.
Before you start: preparation
Begin by choosing good hosting that actually solves your problem rather than just moving it somewhere new. Check the PHP version, limits and disk space. Also make a full, fresh backup of the current site so you have a point to return to if something goes wrong.
WordPress migration step by step
1. Copy the files and the database
Download all the site files (the WordPress directory with plugins, theme and uploads) and export the database. These are the two pillars of WordPress: files are the look and features, the database is the content, settings and users. You need both complete.
2. Upload everything to the new server
On the new host, create a database, import your earlier export into it and upload the files. Then set the new database credentials in wp-config.php (database name, user, password, host). This is the most common place for migration errors, so it is worth double-checking.
3. Test the site on a temporary address
Before you touch the domain, open the site on the new server using a temporary address (the host provides one) or a local address override. Click the key pages, the contact form, the panel login, and in a shop the cart and checkout. This is the moment to catch problems before visitors see them.
4. Switch the domain (DNS)
Once the site works on the new server, change the domain's DNS records to point to the new host. How the individual records work is explained in DNS records: A, CNAME, MX in plain language. The change „propagates" over a dozen minutes to about a day, so during that time it is worth leaving the old site running so everyone lands on a working version.
5. Finish SSL and email
On the new server, issue a new SSL certificate so the site keeps working over HTTPS and no expired certificate warning appears. If you are moving email too, take care of the mailboxes and mail records. Finally set up monitoring so you know right away that the new site runs stably.
What people most often forget
The most common slip-ups are: migrating without a backup, switching the domain before testing the site, a forgotten new SSL certificate, skipped email, and old „hard-coded" addresses left in the database. A separate topic is Google rankings: moving the server alone does not hurt them, because the page URLs do not change. The risk only appears when you also change the URL structure, which we cover in migrating without losing rankings.

Migration is one of those topics where a small mistake costs hours of stress, while a well-done one passes unnoticed. If you want to move WordPress to a faster, more stable server without downtime or stress, get in touch and we will handle the whole migration and testing.
