Prerequisites

  • Supabase project
  • Access to Supabase Dashboard
  • Xata account and project setup
  • Network access to your Supabase database

​
Install and Configure the Xata CLI

Install the Xata CLI: 
curl -fsSL https://xata.io/install.sh | bash

postgresql://your_username:your_password@db.[YOUR-PROJECT-REF].supabase.co:5432/postgres

​
SSL Configuration

Supabase requires SSL by default. Include SSL parameters in your connection string: 
postgresql://your_username:your_password@db.[YOUR-PROJECT-REF].supabase.co:5432/postgres

​
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@db.project-ref.supabase.co:5432/postgres"

# 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;
