Are you looking for steps to migrate a database from MySQL to PostgreSQL using pgLoader? Take a peek at this blog for the migration steps.

pgLoader is a great tool to migrate a database from one database engine to another.

Here at Bobcares, we often receive requests relating to database migration as part of our Server Management Services for web hosts and online service providers.

Today, in this blog we are going through the process of migrating the database from MySQL to PostgreSQL.

How to migrate database from MySQL to PostgreSQL

Now let us see how our Support Engineers migrate the database for our customers.

Recently, one of our customers approached us with the request to migrate his database from MySQL to PostgreSQL. Here are the steps that we followed to do the same.

Set up pgLoader

First, we connect to the compute instance using SSH.

Next, we update the apt packet cache and upgrade the software already installed on the instance. For that, we run the below command.

apt update && apt upgrade -y

Then, we install pgLoader using the apt packet manager. For that, here is the command that we run.

apt install pgloader

In order to check if the installation of pgLoader was successful, we run the following command:

pgloader --version

As a result, the below output displays.

pgloader version "3.4.1"
compiled with SBCL 1.3.3.debian

Thus, now the pgLoader is installed. So, now we can start with the migration process.

Migrating the Database

Now, it’s time to migrate the database. Using pgLoader, we can conveniently migrate the database with a single command.

pgloader mysql://mysqluser:password@<mysql-server>:<mysql-port>/<source-database> postgresql://<pgsql-role>:password@<pgsql_server>:<postgresql-port>/<target-database>

This command will automatically migrate the current database to the managed database instance. However, the migration time may vary depending on the size of the database.
