Moving your website to a new host can be a daunting and stressful experience, but it doesn’t need to be. Even though there are important steps to migrate your WordPress site if you follow our guide you can succeed.
Many people are faced with the need to move to a new host because of problems with their current provider and have just had enough. But all too often, migrating to a more reliable host is delayed time and again for fear of making a mistake and damaging your site(s).
To get around the problem, people will may pay a large fee for a professional to move their site for them. Or search for a new host that offers a migration service as part of a new hosting package. And then there are the people reading this article who take the third option of having a go at it themselves.
If you spend a little time preparing your own website, migrating is nothing to be concerned about. It can be a very straightforward project if approached correctly and can easily be reversed out of should any problems occur.
Let’s run through the steps required to move your WordPress website to a new host, but before we get started showing you how you can migrate your site, please keep in mind that many of the best WordPress hosting companies will actually move your site for you, so if you have just purchased a new hosting plan and are looking to move your site check with your new hosting provider first to see if they offer free migration.

The very first step before migrating is to back up every aspect of your site. This should be a part of your general WordPress security, and is good practice before any major change. But it is also a requirement of migrating your WordPress installation since there is so much data being moved.
So how do you back up your site? There are plenty of plugins you can use to backup WordPress for you such as All in one wp migration. With a backup plugin you typically install and then use built-in settings to manage which files get backed up, how often and where your backups are stored.
Alternatively you can take a more manual approach. To give you a quick summary, manual backups require a file transfer tool (FTP) in order to access your website files. Two popular FTP programs are FileZilla (PC) and Transmit (Mac). After installing you’ll need to use SFTP credential (from your web host account) to connect to your website’s server. Once you’ve connected select and download all files under your website’s directory. This includes the .htaccess file that is set to be hidden. Consult your FTP program’s help file to have it display hidden files if you are unable to see this file.
Depending on the number of media uploads you have in your site, this could take some time. While this download is underway we can begin step two and make a copy of your database.
Exporting your database is a simple process that only requires a few steps to complete. Login to the cPanel account of your web server and open the phpMyAdmin application. Select the database that contains your WordPress installation from the list on the left hand sidebar and once selected click on the Export tab on the navigation menu.
The default settings of a Quick export and the SQL format for the export are sufficient for what we need. Click the Go button and the database export process will begin and a file will be downloaded to your local computer.
Once the database export and the FTP transfer of your files have both completed, you are ready to move onto the next stage.
Before we can begin the migration to the new web host, we need to create an environment for a WordPress installation. To do this you must create a database that you can import your SQL data into.
Login to your new web host with the user credentials they have supplied you and connect to the cPanel software. For our guide we will be using the MySQL Databases application. If your web host doesn’t have that application running then you will should contact their support team to discover their method of creating new databases.
The steps to create a database are quite simple:
Write down the database name, the new MySQL username and its password. You will need them soon.
Browse to the folder on your local computer where you downloaded your website files to. In that folder there is a file called wp-config.php that controls the access between WordPress and your database.
Make a copy of this file and store it in another folder on your local computer. This is necessary for restoring the changes we are about to make should something go wrong later.
Open the original version of the file with your favorite text editor and make the following three changes:
Locate the following line:
The db_name portion of this line will currently be set to the MySQL database name of your old web host. This must be changed to the name of the new database you have just created.
Below this you will find the line:
In this line you need to change the db_user portion from the username of your old host to match the new username you have just created.
Finally, edit the third line:
As with the others the db_pass section of this line must be changed to the new secure password you created for your MySQL user.
Save wp-config.php and close the file.
Now that you have a new database to work with we can begin the import process.
Launch phpMyAdmin from the cPanel software on your new server and select your new database from the list on the left hands sidebar. Once it opens select the Import tab from the navigation menu.
In the File to Import section click the Choose File button and select the SQL file you exported previously.
Un-tick the Partial Import check box, make sure the format is set to SQL and then click the Go button. The database import will now begin.
The time this import takes varies depending on the size of your database. You should receive a message informing you of the success of the import when it has finished.
Now that you have the new database prepared and you’ve reconfigured the wp-config.php file, it is time to begin uploading your website’s files.
Connect to your new web host using your FTP program and browse to the folder that your website is going to be held. If this is the primary, or only site being installed on this web server then uploading the files to the public_html folder is the usual directory.
With the remote directory selected you can upload your website files that should now include the updated version of wp-config.php. As with the earlier download, this process can take some time.
Don’t delete these files from your local computer once the upload finishes. They are still needed until the final steps have been completed.
If you are moving to a new/different domain then you should read over this step, if not, then you can skip this because you don’t have to update your site to point to a different domain.
One issue people always seem to have when moving their site is that they’ve added links to other posts on their site or inserted images directly by pointing to a URL on the server, causing these to break when moved over to a new domain. If you want to quickly and easily search for any instances of your old domain name and replace with the new name we suggest you take a look at the Search Replace DB script on github. This will allow you to do this with great ease. Just make sure you DELETE it when your are done (for security reasons) and don’t place it in your root domain, create a temp folder with a random name to host the script.
Changing Site URL: By doing a search and replace for the old domain and replacing with the new domain you’ll also be altering the site_url and home url values in the database (Changing the Site URL) which will ensure that when you try to log into your site on the new domain it doesn’t try and redirect you over to the old domain.
This step actually includes two separate mini steps with (potentially) several days between them.
First – before you can use the site on your new host you will need to reconfigure your domain’s DNS settings. They will be set to point to your old host and you will need to point the correct records to the new server IP address.
This process will depend on where you have your domain registered. The details of completing this process are too varied to discuss in this post, but your domain registrar should have all of the details you need to make this change.
DNS changes can take up to 48 hours to fully propagate. It’s best to do this at a period when you expect lower levels of traffic. During this 48 hour window you should avoid making any changes to your website as you may be changing the old version of the site.
Second – after the 48-hour period has expired you should now be accessing the new web host when you go to your website. It’s at this point you can connect to your old web host to delete the files and database. You should still have a local backup copy of these files and the database export, along with the original wp-config.php file in case you need to roll back the migration. It can be a good idea to hold onto these files for a an extended period just to be on the safe side.
As you can see, when broken down into the above simple steps, the process isn’t that difficult. All it really requires is for you to be careful at each step and give yourself the option to go back to the original version until the last possible moment (in case of any problems).
