​
Prerequisites

  • Google AlloyDB PostgreSQL cluster
  • Access to Google Cloud Console
  • Xata account and project setup
  • Network access to your AlloyDB cluster

​
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 AlloyDB cluster has a public IP:
  1. Authorize Your IP:
    • Go to your AlloyDB cluster → “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 AlloyDB cluster → “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 AlloyDB cluster

​
Option 3: AlloyDB Auth Proxy

Use AlloyDB Auth Proxy for secure connections: 
# Install AlloyDB Auth Proxy
curl -o alloydb-auth-proxy https://storage.googleapis.com/alloydb-auth-proxy/v1.0.0/alloydb-auth-proxy.linux.amd64
chmod +x alloydb-auth-proxy

# Start the proxy
./alloydb-auth-proxy --instances=your-project:your-region:your-cluster

​
Get Connection String

​
Connection String Format

postgresql://your_username:your_password@your-alloydb-ip:5432/your_database?sslmode=require

​
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-alloydb-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 and configure anonymization rules
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
