How to Migrate from Microsoft SQL Server to PostgreSQL ​

Skippr is the easiest way to migrate from MSSQL to PostgreSQL and get fully cleansed and modeled data in one run command.

Source: MSSQL. Destination: PostgreSQL.

Sample config ​

yaml
skippr:
  workspace: mssql_to_postgres
pipelines:
  mssql_to_postgres:
    data_source: data_sources.source
    data_sink: data_sinks.warehouse
data_sources:
  source:
    Mssql:
      connection_string: "${MSSQL_CONNECTION_STRING}"
data_sinks:
  warehouse:
    Postgres:
      host: localhost
      port: 5432
      user: ${POSTGRES_USER}
      password: ${POSTGRES_PASSWORD}
      database: analytics
      schema: public

Environment ​

bash
export POSTGRES_HOST="localhost"
export POSTGRES_USER="myuser"
export POSTGRES_PASSWORD="mypassword"
export MSSQL_CONNECTION_STRING="server=tcp:127.0.0.1,1433;database=testdb;user id=sa;password=YourPass;TrustServerCertificate=true"

Source connector: mssql. Destination connector: postgres-warehouse.
