You can use the posts above to install the same servers and packages you have on your current server. Just make sure to install specific packages on your new server using the identical posts mentioned.

Once all the packages are installed, you can transfer content from your current server to the new one.

Configure your new Google server similar to your current server

Configuring your new Google Cloud server to be similar to your current one is crucial for a smooth WordPress migration, especially matching web server settings.

Make sure the web server (Apache or Nginx) settings are the same on both old and new servers. This includes the same directory structure and Virtual Host or Server block content. You can find guides on setting up these configurations in the links below:

• Apache directory: /etc/apache2/
• Nginx directory: /etc/nginx/

Your PHP configuration should also be identical to your current server’s PHP settings. Use the post above to install a specific PHP version and all the modules you have on your current server.

• PHP directory: /etc/php/

Your MySQL or MariaDB configurations should also mimic your current server. Validate each file, directory, and other data to ensure your new server is no different from your current server before migration.

• MySQL / MariaDB directory: /etc/mysql/

Once you’ve completed these checks, you can continue with the migration process.

Back up current server data and database before migration

Backing up your current server’s website files and database is a vital step before you migrate your WordPress site to Google Cloud.

First, you need to back up your WordPress website content and your database content. It’s essential to back up both the website files and the data within the database.

At this point, stop all changes on your current server before backing it up. You won’t want new changes added after the backup is complete.

To back up WordPress content, log into your server via SSH. Once in your current server’s SSH console, run the commands below to back up your WordPress content, usually located at /var/www/html/.

When you run the commands below, a backup file named current-server-backup.tar will be created containing your WordPress content.

sudo tar -cvf current-server-backup.tar /var/www/html/

Next, back up your database content. Again, you need to use the root account or an account with full access to the database you wish to back up.

To back up all databases on the server, run the commands below:

sudo mysqldump -u username –p --all-database > all_databases_backup.sql

A file named all_databases_backup.sql should also be created in the current working directory.

You should now have two files: current-server-backup.tar and all_database_backup.sql.

Copy the current server’s content to the Google Cloud server

At this point, you should be ready to copy the current server’s content over to your new server. There are several ways to transfer the tar and SQL data files.

You can use the rsync command from the new server. SSH into it and use a command similar to the one shown below (remember to change the host names as needed).

While connected to your Google Cloud console, run the commands below to connect to your current server and copy over the backed-up content.

rsync -avz user@old-server.com:/home/<username>/all_database_backup.sql
rsync -avz user@old-server.com:/home/<username>/current-server-backup.tar

You could also use SCP to copy your files securely. The syntax looks like this:

scp user@old-server.com:/home/<username>/all_database_backup.sql /home/username/
scp user@old-server.com:/home/<username>/current-server-backup.tar /home/username/

If you can’t get the files using SSH, you can use the wget command to download the files to your new Google Cloud server.

You must copy the files to the current server’s web server root directory to use the commands below.

cd ~
wget http://old-web-site.com/all_database_backup.sql
wget http://old-web-site.com/current-server-backup.tar

Once the files are copied to your new server, continue to extract them below and import the database content into your database server.

Restore the current server’s content to the Google Cloud server

Restoring your current server’s content to the Google Cloud server involves extracting your website files and importing your database.

tar -xvf current-server-content.tar
sudo cp -rf /var/www/html/ /var/www/html/

Next, run the commands below to import the database content to your servers.

sudo mysql -u root -p < all_database_backup.sql

At this point, your Google server should have the current server and database content. Next, run the commands below to set up the correct permissions.

Validate that all configurations on your current server match your new Google Cloud server. Once everything is validated, restart your web server.

sudo systemctl restart nginx
sudo systemctl restart apache2

If you encounter an error, make sure to resolve it.

Update your DNS and point your domain to your new Google server IP address

Updating your DNS to point your domain to your new Google Cloud server IP address is the final step to make your migrated WordPress site live.

Once your local test is successful, log in to your DNS provider portal and update the DNS A record to point to your new server IP address.

If everything works, you can continue fine-tuning your new server to ensure all configurations are correct.

That should do it!

How to set up and connect to your Google Cloud server

Setting up your Google Cloud server involves creating a virtual machine, called a Compute Engine instance, which will host your WordPress site.

Google Cloud servers, specifically Compute Engine, let you connect to your virtual machine (VM) instance directly from your browser via SSH within the Google Cloud Console.

SSH from the browser supports the following:

• Web browsers
  • The latest version of Google Chrome
  • Firefox
  • Microsoft Edge
  • Microsoft Internet Explorer 11 and later
  • Safari 8 and later. Note that Safari is not supported in private browser mode.
• Virtual machine configurations
  • All Linux VM images are natively available in Google Cloud.

You won’t need extra software or browser extensions. Log into the Google Cloud Console, then go to Menu > Compute Engine > VM instances.

Click the SSH button next to the instance you want to connect to. You can also click its name and then click SSH on the instance details page.

This opens an SSH terminal window for your Ubuntu Linux instance, where you can now run commands.
