Migrate from GCP Cloud SQL to Xata

Learn how to migrate your GCP Cloud SQL PostgreSQL database to Xata using xata clone. Step-by-step instructions for configuring the migration.

Prerequisites

  • GCP Cloud SQL PostgreSQL instance
  • Access to Google Cloud Console
  • Xata account and project setup
  • Network access to your Cloud SQL instance

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 IP (Less Secure)

If your Cloud SQL instance has a public IP:

  1. Authorize Your IP:
    • Go to your Cloud SQL instance → "Connections" → "Networking"
    • Add your IP address to "Authorized networks"
    • Or temporarily add 0.0.0.0/0 for migration (remove after)

For better security, use private IP:

  1. Enable Private IP:

    • Go to your Cloud SQL instance → "Connections" → "Networking"
    • Enable "Private IP"
    • Configure VPC peering if needed

  2. Run Migration from GCP:

    • Use Cloud Run, Compute Engine, or Cloud Functions
    • Ensure the service is in the same VPC as your Cloud SQL

Option 3: Cloud SQL Proxy

Use Cloud SQL Proxy for secure connections:

# Install Cloud SQL Proxy
curl -o cloud-sql-proxy https://dl.google.com/cloudsql/cloud-sql-proxy.linux.amd64
chmod +x cloud-sql-proxy

# Start the proxy
./cloud-sql-proxy --instances=your-project:your-region:your-instance

Get Connection String

postgresql://your_username:your_password@your-cloudsql-ip:5432/your_database?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-cloudsql-ip:5432/your_database?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:

    psql `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
