+# Chat Database Migration Guide
+
+This guide will help you migrate your chat database from the current server to a new PostgreSQL server.
+
+## Overview
+Your chat system uses:
+- Database: `rocketchat_converted` (PostgreSQL)
+- Main tables: users, message, room, uploads, avatars, subscription
+- File storage: db-convert/db/files/ directory with uploads and avatars
+- Environment configuration for database connection
+
+## Migration Steps
+
+### 1. Pre-Migration Setup
+
+On your **new server**, ensure PostgreSQL is installed and running:
+```bash
+# Install PostgreSQL (if not already done)
+sudo apt update
+sudo apt install postgresql postgresql-contrib
+
+# Start PostgreSQL service
+sudo systemctl start postgresql
+sudo systemctl enable postgresql
+```
+
+### 2. Create Database Schema on New Server
+
+Run the provided migration script:
+```bash
+# On new server
+sudo -u postgres psql -f create-new-database.sql
+```
+
+### 3. Export Data from Current Server
+
+Run the export script:
+```bash
+# On current server
+./export-chat-data.sh
+```
+
+This will create:
+- `chat-schema.sql` - Database schema
+- `chat-data.sql` - All table data
+- `chat-files.tar.gz` - All uploaded files and avatars
+
+### 4. Transfer Data to New Server
+
+```bash
+# Copy files to new server
+scp chat-schema.sql chat-data.sql chat-files.tar.gz user@new-server:/tmp/
+```
+
+### 5. Import Data on New Server
+
+```bash
+# On new server
+./import-chat-data.sh
+```
+
+### 6. Update Configuration
+
+Update your environment variables to point to the new database server.
+
+### 7. Verify Migration
+
+Run the verification script to ensure everything transferred correctly:
+```bash
+node verify-migration.js
+```
+
+## Files Provided
+
+1. `create-new-database.sql` - Creates database and user on new server
+2. `export-chat-data.sh` - Exports data from current server
+3. `import-chat-data.sh` - Imports data to new server  
+4. `verify-migration.js` - Verifies data integrity
+5. `update-config-template.env` - Template for new configuration
+
+## Important Notes
+
+- **Backup first**: Always backup your current database before migration
+- **Downtime**: Plan for application downtime during migration
+- **File permissions**: Ensure file permissions are preserved during transfer
+- **Network access**: Ensure new server can accept connections from your application
