SQL Server to PostgreSQL conversion and synchronization.

DBConvert / DBSync database migration software automates the conversion and synchronization of your data from Microsoft SQL Server to PostgreSQL and vice versa. Transfer the database schema, all data, or select only the required data set during the configuration pass in an easy-to-use, wizard-style graphical interface.

Why Migrate from MS SQL Server to PostgreSQL?

1. The main advantage of PostgreSQL over SQL Server is the licensing cost. PostgreSQL is completely free, and the cost of an MSSQL server depends on the number of users and the size of a database.
2. SQL Server from Microsoft is a proprietary database instead of PostgreSQL, which is developed and maintained by a global community of open source developers and companies.
3. Another good reason to try Postgres from a DBA perspective is high availability. If you have any requirements (HA) and cannot afford even a standard SQL Server edition license, go Postgres.
4. Cross-platform support was another PostgreSQL advantage until Microsoft released SQL Server for Linux in 2017. Both database engines are now available for Windows and Linux. For other deployment scenarios, you can use Docker containers and database clusters on Kubernetes.

Although Microsoft SQL Express is free, it is heavily limited compared to other editions of SQL Server. So if the pricing is an issue, then you should switch to PostgreSQL.

Data type Mapping.

MS SQL Server and PostgreSQL databases are ANSI-SQL compliant. But there are still differences between SQL syntax, data types, and case sensitivity. Mapping data types from SQL Server to PostgreSQL manually isn't all that trivial. Built-in data mapping in DBConvert tools helps to map SQL Server data types to Postgres data types automatically. Besides, there is a manual way to map data types.

Disadvantages of some open-source tools.

While there are some free open source solutions like Pgloader or Sqlserver2pgsql, there are some drawbacks to using them.

• These are command-line utilities, so they don't have a graphical interface. For those who are intimidated by the terminal, they are not easy to use.
• These tools are limited to one-way migrations where PostgreSQL can be configured as a destination.

Six reasons to use DBConvert for migrating from SQL Server to PostgreSQL?

1. DBConvert tools are highly customizable and allow you to quickly and easily export data from SQL Server to Postgres using a comprehensive graphical interface. The DBConvert apps guide you through a few steps, from connecting to the source and target databases, configuring many parameters, and scheduling subsequent launches.
2. In any combination, data conversion and synchronization between the following databases are possible:
   • Microsoft SQL Server,
   • Windows Azure SQL Databases/ Azure SQL Data Warehouse,
   • Google Cloud SQL for SQL Server,
   • AWS RDS/ Aurora,
   • CockroachDB,
   • Google Cloud SQL for PostgreSQL,
   • Heroku Postgres
3. The new DBConvert parallel migration mechanizm is optimized to take full advantage of modern multi-core processors. That speeds up data migration between databases by splitting tables into multiple parts and processing them in parallel.
4. DBSync software keeps your databases in Sync with Update, Insert, and Drop synchronization features.
5. Bi-directional synchronization helps to update data in both source and destination databases simultaneously.
6. Trigger-based Synchronization algorithm is developed to accurately analyze the destination database data and instantly track changes in both databases. The trigger-based sync method increases recurrent synchronization speed in times.
