Setup

Requirements

  • Git
  • NodeJS > v8

Clone git project

git clone https://github.com/smartexpose/mysql-postgresql-converter.git

Install dependencies

npm install

Configuration

You must enter the necessary credentials and details in config/config.json. The file contains a brief description of each required parameter. Make sure to configure:

  • username (PostgreSQL superuser, usually "postgres")
  • See here for information on superuser

Usage

Create a new PostgreSQL database

CREATE DATABASE my_postgresql_database;

Note:

If you are planning to migrate spatial data (geometry type columns), then PostGIS should be installed and enabled.

Build and run

npm run build
npm start

If the migration failed, simply restart the process.

npm start

Once the migration is finished, check log file in logs_directory for possible errors

Tests

Create a new PostgreSQL Test database

CREATE DATABASE nmig_test_db;

You can use test_config.json to configure the test DB environment, and adjust according to your test environment.

Build and run

npm run build
npm start
