+# Synchronizing Data Between Two Cyberwatch Instances
+
+This script lets you synchronize asset data from a **source Cyberwatch instance (Instance A)** to a **destination instance (Instance B)** using the Cyberwatch Python CLI.
+
+This process is useful for air-gapped networks, backup purposes, or centralized analysis of vulnerability data.
+
+---
+
+## API Key Requirements
+
+- Instance A (source): API key with **read-only** permissions  
+- Instance B (destination): API key with **full access** permissions
+
+Make sure your Cyberwatch CLI or environment is configured with the appropriate API key for each step below.
+
+> If you get an `"api_url not found"` error, place `sync_assets.py` inside the `examples` directory and run it again.  
+
+---
+
+## Step 1 – Export Data from Instance A
+
+> Use the **read-only** API key from **Instance A**
+
+The Python script `sync_assets.py` fetches all assets from Instance A and saves their vulnerability data in `.txt` files.
+
+Each `.txt` file corresponds to a single asset and is saved in the `export` directory (created automatically if it doesn't exist).
+
+Run the script with:
+
+```bash
+python3 sync_assets.py
+```
+
+Output files will be located in the `export/` folder relative to where the script is run.
+
+---
+
+## Step 2 – Upload Data to Instance B
+
+> Use the **full-access** API key from **Instance B**
+
+1. Switch your API configuration to use the **Instance B full-access** API key  
+2. Go to the `export/` directory where the `.txt` files were saved  
+3. Upload all `.txt` files using:
+
+```bash
+cyberwatch-cli airgap upload export/*.txt
+```
+or
+```bash
+find ./export -name "*.txt" -exec sudo cyberwatch-cli airgap upload {} \;
+```
+
+> On Windows, the CLI automatically uploads files from the `uploads` folder by default.  
+> To use the `export` directory, provide the full path to your `.txt` files.
+
+---
+
+## Result
+
+- All assets from Instance A are successfully transferred to Instance B  
+- Instance B automatically analyzes and recalculates vulnerability information upon upload
