​
Prerequisites

  • AWS Aurora PostgreSQL cluster
  • Access to AWS Console
  • Xata account and project setup
  • Network access to your Aurora 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 Endpoint (Less Secure)

If your Aurora cluster has a public endpoint:
  1. Whitelist Your IP:
    • Go to your Aurora cluster → Security Groups
    • Add a rule allowing PostgreSQL (port 5432) from your IP address
    • Or temporarily allow from anywhere (0.0.0.0/0) for migration
For better security, run the migration from within AWS:
  1. EC2 Instance in Same VPC:
    • Launch an EC2 instance in the same VPC as your Aurora cluster
    • Install Xata CLI on the EC2 instance
    • Run the migration from there
  2. GitHub Actions with AWS Credentials:
    • Use GitHub Actions with AWS credentials
    • Configure the action to run in your VPC
    • Use the private endpoint for connection

​
Get Connection String

postgresql://your_username:your_password@your-aurora-endpoint:5432/your_database
You can find the endpoint in the AWS Aurora Console under your cluster details.

​
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-aurora-endpoint:5432/your_database"

# 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
