Migrate from Azure Database for PostgreSQL to Xata

Learn how to migrate your Azure Database for PostgreSQL to Xata using xata clone. Step-by-step instructions for configuring the migration.

Prerequisites

  • Azure Database for PostgreSQL instance
  • Access to Azure Portal
  • Xata account and project setup
  • Network access to your Azure database

Install and Configure the Xata CLI

Install the Xata CLI:

curl -fsSL https://xata.io/install.sh | bash

Authenticate with your Xata account:

xata auth login

Network Configuration

Option 1: Public Access (Less Secure)

If your Azure database allows public access:

  1. Configure Firewall Rules:
    • Go to "Networking" in the left menu
    • Add your IP address to "Firewall rules"
    • Or temporarily add 0.0.0.0/0 for migration (remove after)

For better security, use private endpoints:

  1. Enable Private Endpoint:

    • Go to "Networking" in the left menu
    • Enable "Private endpoint connections"
    • Configure VNet integration

  2. Run Migration from Azure:

    • Use Azure VM, App Service, or Azure Functions
    • Ensure the service is in the same VNet as your database

Option 3: Azure Database for PostgreSQL Flexible Server

If you're using Flexible Server:

  1. Configure Network Access:
    • Go to "Networking" in the left menu
    • Choose "Private access (VNet Integration)" or "Public access"
    • Configure firewall rules accordingly

Get Connection String

Azure connection strings typically look like this:

postgresql://your_username:your_password@your-server.postgres.database.azure.com:5432/postgres?sslmode=require

Replicate Database Roles

Before migrating your data, you'll need to replicate the database roles from your source database to your Xata branch.

Extract Roles from Source Database

Connect to your source database and extract the role definitions:

-- Extract role definitions (run this on your source database)
SELECT 
    'CREATE ROLE ' || rolname || ' WITH ' ||
    CASE WHEN rolcanlogin THEN 'LOGIN ' ELSE 'NOLOGIN ' END ||
    CASE WHEN rolsuper THEN 'SUPERUSER ' ELSE 'NOSUPERUSER ' END ||
    CASE WHEN rolinherit THEN 'INHERIT ' ELSE 'NOINHERIT ' END ||
    CASE WHEN rolcreaterole THEN 'CREATEROLE ' ELSE 'NOCREATEROLE ' END ||
    CASE WHEN rolcreatedb THEN 'CREATEDB ' ELSE 'NOCREATEDB ' END ||
    CASE WHEN rolreplication THEN 'REPLICATION ' ELSE 'NOREPLICATION ' END ||
    CASE WHEN rolbypassrls THEN 'BYPASSRLS ' ELSE 'NOBYPASSRLS ' END ||
    'CONNECTION LIMIT ' || COALESCE(rolconnlimit, -1) || ';' as create_role_statement
FROM pg_roles 
WHERE rolname NOT LIKE 'pg_%'
ORDER BY rolname;

Apply Roles to Xata Branch

  1. Connect to your Xata branch:

    psql `xata branch url`

  2. Execute the role creation statements from the previous step

Initialize Xata Project

Set up your Xata project configuration:

xata init

Configure the Migration

Set up your clone configuration with optional anonymization:

# Set your source URL
export XATA_CLI_SOURCE_POSTGRES_URL="postgresql://your_username:your_password@your-server.postgres.database.azure.com:5432/postgres?sslmode=require"

# Configure anonymization rules
xata clone config --source-url $XATA_CLI_SOURCE_POSTGRES_URL --mode prompt

Start the Migration

Begin the data transfer:

# Start the migration
xata clone start --source-url $XATA_CLI_SOURCE_POSTGRES_URL

Monitor Progress

Check the migration status:

xata clone status

Verification

After migration, verify your data:

  1. Connect to Xata Branch:

    xata branch url

  2. Check Data Integrity:

    -- Compare row counts
SELECT COUNT(*) FROM your_table;

-- Check sample data
SELECT * FROM your_table LIMIT 10;

  3. Test Relationships: Verify foreign key relationships work correctly
