MySQL is a relational database management system that uses Structured Query Language (SQL). It's used to manage information stored on computers, whether it's personal data or vast amounts of information within a company. Thanks to this free database management system, businesses can easily support their operations. So, how do you migrate a database between two servers to keep this data safe?

Follow our step-by-step guides to move your MySQL database to another server using a third-party database transfer tool, or MySQL's backup program. These methods work for migrating a database in Windows.

(The simplest way) How to transfer a MySQL database from one server to another

No need to learn the command lines mentioned in other articles, you can move MySQL database with just a few clicks. That's why the Todo PCTrans tool stands out. All you need to do is download this database migration tool and execute 3 simple steps. Trust the tool! We specialize in transferring database from one server to another.

Click to download the trial version:

Step 1: Run Todo PCTrans on both computers

On the source computer, click Computer to Computer under Tools on the Todo PCTrans main interface, and then proceed.

Step 2: Choose the transfer direction - from the old computer or to the new one.

"New" - Transfer all data from an old computer to the current new one, remotely.

"Old" - Transfer all data from your current old device to the new one.

Select transfer direction:

Step 3: Connect the two computers

1. Select the IP address or device name of the target computer, then click "Connect."

2. Type the login password for the target computer, then click OK to confirm.

If the target PC is not listed, you can also click Add PC to manually connect to it by entering the IP address or device name.

Step 4: Select applications, programs, and software to transfer to the target computer

1. You can select and transfer the content you need from the source computer to the target computer.

2. After selecting the apps and data you want to transfer, click “Transfer” to start the process.

If you want to perform a remote transfer, you can try using Todo PCTrans in "Backup and Restore" mode. In the next section, we will go through the procedure of backing up a database with mysqldump so that it is saved as a single file.

How to Migrate a Database to a Target Server

To move a database between two servers, you would use Mysqldump, a command-line utility that can create backups of MySQL databases, essentially cloning them.

First, you need to export the database to a Dump file. Then transfer it to the target server. Finally, import the MySQL database on the new server.

First Step: Export the MySQL database to a dump file

Log in to your old server and enter the systemctl command to stop the MySQL service:

Stop the MySQL Service

Use the `mysqldump` command to export the database as a dump file:

Export all MySQL databases: mysqldump -u [username] -p --all-databases > all_databases.sql

Export a single database: mysqldump -u root -p --opt [database_name] > database_name.sql

Step 2: Transfer the MySQL database to the new server using the SCP command

SCP is a file transfer program that you can install on Linux. To use it, enter the SCP command line in your terminal. If that doesn't work, download SCP first. Alternatively, go back and use the Todo PCTrans tool.

For all databases: scp all_databases.sql user@example.com:~/

Single database: Single database: scp database_name.sql username@example.com:~/

When it's done, your database should be visible on the new server.

Step 3: Import the database into MySQL

Please run the following command in the terminal to import the MySQL database dump file into the new server: ```bash mysql -u [username] -p[password] -h [new_server_ip] [database_name] < [path_to_dump_file.sql] ``` Replace `[username]` with your MySQL username, `[password]` with your MySQL password, `[new_server_ip]` with the IP address of your new server, `[database_name]` with the name of the database you want to import, and `[path_to_dump_file.sql]` with the actual path to your dump file. For example: ```bash mysql -u root -p123456 -h 192.168.1.100 mydatabase < /home/user/dumpfile.sql ``` Make sure MySQL is running on the new server and you have the necessary permissions to access it.

All databases: mysqldump -u [username] -p --all-databases > all_databases.sql

For a single database: mysql -u [username] -p newdatabase < database_name.sql

More options:

To move a specific table within a MySQL database, use the following command:

mysqldump -u [Username] -p [DatabaseName] [Table1] [Table2] > dump.sql
