+# Migrating Existing Services to Cortex
+
+This guide shows how to migrate your existing services (scout-search, github-package, bluesky-package, cross-platform-linker) to use Cortex for configuration management.
+
+## Benefits of Migration
+
+- ✅ **No more .env files** to manage or accidentally commit
+- ✅ **Encrypted secrets** stored securely in Brainy
+- ✅ **Single source of truth** for all configurations
+- ✅ **Automatic deployment** - configs follow your app
+- ✅ **Version controlled** configs with audit trail
+
+## Step 1: Initialize Cortex
+
+First, set up Cortex with your existing Brainy storage:
+
+```bash
+# In your project root
+npx cortex init
+
+# Choose your existing storage type (S3, etc)
+# This creates .brainy/cortex.json and .brainy/cortex.key
+```
+
+## Step 2: Import Existing Configuration
+
+### Option A: Import from .env file
+```bash
+# Import all your existing environment variables
+cortex config import .env
+cortex config import .env.production
+
+# Cortex automatically encrypts sensitive values (keys, tokens, passwords)
+```
+
+### Option B: Set manually with encryption
+```bash
+# For scout-search
+cortex config set OPENAI_API_KEY sk-... --encrypt
+cortex config set DATABASE_URL postgres://... --encrypt
+cortex config set PORT 8080
+
+# For github-package  
+cortex config set GITHUB_TOKEN ghp_... --encrypt
+cortex config set GITHUB_API_URL https://api.github.com
+
+# For bluesky-package
+cortex config set BLUESKY_HANDLE alice.bsky.social
+cortex config set BLUESKY_PASSWORD ... --encrypt
+cortex config set BLUESKY_SERVICE wss://bsky.social
+
+# For cross-platform-linker
+cortex config set SERVICES.github https://github-package.run.app
+cortex config set SERVICES.bluesky https://bluesky-package.run.app
+cortex config set SERVICES.scout https://scout-search.run.app
+```
+
+## Step 3: Update Your Service Code
+
+The migration requires **only ONE line** of code change:
+
+### scout-search/src/index.js
+```javascript
+// Before
+import { BrainyData } from '@soulcraft/brainy'
+import dotenv from 'dotenv'
+
+dotenv.config()  // ← Remove this
+
+const brainy = new BrainyData({
+  storage: {
+    type: 's3',
+    bucket: process.env.S3_BUCKET,  // Still works!
+    // ...
+  }
+})
+
+// After - Add just this line
+await brainy.loadEnvironment()  // ← ADD THIS LINE
+
+// All your process.env variables are now loaded from Cortex!
+console.log(process.env.OPENAI_API_KEY)  // Works, decrypted automatically!
+```
+
+### github-package/index.js
+```javascript
+import { BrainyData } from '@soulcraft/brainy'
+
+const brainy = new BrainyData({ /* your config */ })
+
+// Add this ONE line at startup
+await brainy.loadEnvironment()
+
+// Now all configs are available
+const githubToken = process.env.GITHUB_TOKEN  // Decrypted automatically!
+const apiUrl = process.env.GITHUB_API_URL
+```
+
+### bluesky-package/src/index.ts
+```typescript
+import { BrainyData } from '@soulcraft/brainy'
+
+export class BlueskyPackage {
+  async init() {
+    const brainy = new BrainyData({ /* config */ })
+    
+    // Load all configurations
+    await brainy.loadEnvironment()
+    
+    // Use as normal
+    this.handle = process.env.BLUESKY_HANDLE
+    this.password = process.env.BLUESKY_PASSWORD  // Decrypted!
+  }
+}
+```
+
+## Step 4: Update Deployment Configuration
+
+### Docker
+```dockerfile
+# Before - Complex env management
+FROM node:20
+COPY .env.production .env  # ← Remove this
+ENV AWS_ACCESS_KEY_ID=...   # ← Remove these
+ENV AWS_SECRET_ACCESS_KEY=...
+
+# After - Simple and secure
+FROM node:20
+ENV BRAINY_STORAGE=s3://my-app-data
+ENV CORTEX_MASTER_KEY=${CORTEX_KEY}  # From CI/CD secrets
+# That's it! All other configs loaded from Brainy
+```
+
+### Google Cloud Run
+```yaml
+# Before - Many environment variables
+env:
+  - name: DATABASE_URL
+    value: postgres://...
+  - name: OPENAI_API_KEY
+    valueFrom:
+      secretKeyRef:
+        name: openai-key
+  # ... many more
+
+# After - Just two!
+env:
+  - name: BRAINY_STORAGE
+    value: s3://my-app-data
+  - name: CORTEX_MASTER_KEY
+    valueFrom:
+      secretKeyRef:
+        name: cortex-key
+```
+
+### GitHub Actions
+```yaml
+# Before
+env:
+  DATABASE_URL: ${{ secrets.DATABASE_URL }}
+  STRIPE_KEY: ${{ secrets.STRIPE_KEY }}
+  OPENAI_KEY: ${{ secrets.OPENAI_KEY }}
+  # ... dozens more
+
+# After
+env:
+  CORTEX_MASTER_KEY: ${{ secrets.CORTEX_MASTER_KEY }}
+  # That's it!
+```
+
+## Step 5: Gradual Migration Strategy
+
+You can migrate gradually without breaking existing deployments:
+
+```javascript
+// Support both old and new config methods during transition
+async function loadConfig() {
+  const brainy = new BrainyData({ /* config */ })
+  
+  try {
+    // Try loading from Cortex first
+    await brainy.loadEnvironment()
+    console.log('✅ Configs loaded from Cortex')
+  } catch (error) {
+    // Fall back to .env if Cortex not configured
+    console.log('📁 Using .env file (legacy)')
+    require('dotenv').config()
+  }
+}
+```
+
+## Step 6: Coordinate Multi-Service Updates
+
+When you need to update configuration across all services:
+
+```bash
+# Update a config value
+cortex config set API_VERSION v2
+
+# All services automatically get the update!
+# No need to redeploy or restart
+```
+
+For storage migration across all services:
+
+```bash
+# Coordinate migration to new storage
+cortex migrate --to s3://new-bucket --strategy gradual
+
+# All services (scout-search, github-package, etc) 
+# automatically detect and migrate!
+```
+
+## Complete Migration Example
+
+Here's a complete migration for scout-search:
+
+### 1. Setup Cortex
+```bash
+cd ~/Projects/scout-search
+npx cortex init
+# Choose S3, enter bucket details
+```
+
+### 2. Import existing config
+```bash
+cortex config import .env.production
+```
+
+### 3. Update code (src/index.js)
+```javascript
+import { BrainyData } from '@soulcraft/brainy'
+
+const brainy = new BrainyData({
+  storage: { type: 'auto' }  // Auto-detect from Cortex
+})
+
+// Add this line
+await brainy.loadEnvironment()
+
+// Everything else stays the same!
+const app = express()
+app.listen(process.env.PORT || 8080)
+```
+
+### 4. Update Dockerfile
+```dockerfile
+FROM node:20
+WORKDIR /app
+COPY . .
+RUN npm install
+ENV CORTEX_MASTER_KEY=${CORTEX_KEY}
+CMD ["node", "src/index.js"]
+```
+
+### 5. Deploy
+```bash
+# Build and deploy as normal
+docker build -t scout-search .
+docker run -e CORTEX_MASTER_KEY=$CORTEX_KEY scout-search
+
+# Or to Cloud Run
+gcloud run deploy scout-search \
+  --set-env-vars="CORTEX_MASTER_KEY=$CORTEX_KEY"
+```
+
+## Rollback Plan
+
+If you need to rollback:
+
+1. **Keep .env files** during transition (don't delete yet)
+2. **Use gradual approach** shown in Step 5
+3. **Test in staging** before production
+4. **Backup configs**: `cortex backup --include-config`
+
+## Security Best Practices
+
+1. **Never commit** `.brainy/cortex.key`
+2. **Store master key** in CI/CD secrets
+3. **Rotate periodically**: `cortex security rotate-key`
+4. **Audit access**: `cortex audit --last 30d`
+
+## Troubleshooting
+
+### Configs not loading?
+```bash
+# Check Cortex status
+cortex status
+
+# Verify configs are set
+cortex config list
+
+# Test loading
+cortex env
+```
+
+### Lost master key?
+```bash
+# If you have a backup with configs
+cortex restore backup.json --recover-key
+```
+
+### Service can't connect?
+```javascript
+// Add debug logging
+const brainy = new BrainyData({ /* config */ })
+try {
+  await brainy.loadEnvironment()
+  console.log('Cortex configs loaded:', Object.keys(process.env).length)
+} catch (error) {
+  console.error('Cortex error:', error)
+}
+```
+
+## Summary
+
+Migration is simple:
+1. `npx cortex init` - One time setup
+2. `cortex config import .env` - Import existing configs
+3. `await brainy.loadEnvironment()` - Add one line to your code
+4. Deploy with just `CORTEX_MASTER_KEY` - No more env variable sprawl
+
+Your services are now using encrypted, centralized configuration management with zero external dependencies! 🎉
