Migrating from OpenClaw to Hermes Agent: Zero-Downtime Guide
Why Migrate to Hermes Agent?
OpenClaw was one of the earliest AI agent frameworks, and many users started their journey there. Hermes Agent is the natural successor, built by NousResearch with significant improvements across the board.
Here's what you gain by migrating:
| Feature | OpenClaw | Hermes Agent |
|---------|----------|--------------|
| Model support | ~20 models | 200+ models via OpenRouter |
| Memory system | Basic | Persistent + contextual |
| Skills ecosystem | Limited | 100+ community skills |
| Multi-agent | β | β Sub-agent orchestration |
| Messaging | Telegram only | Telegram, Discord, Slack, Signal |
| Cron scheduling | β | β Built-in |
| MCP support | β | β Full integration |
| Self-learning | Limited | β Skill learning loop |
| Active development | Maintenance | Active (74.9k β) |
Important: This guide assumes you're running OpenClaw v2.x or later. Earlier versions may have different file structures.
Pre-Migration Checklist
Before starting, gather the following from your OpenClaw installation:
# Find your OpenClaw data directory
echo $OPENCLAW_HOME
# Usually: ~/.openclaw
# Check installed skills
openclaw skills list > my-skills-backup.txt
# Export conversation history
openclaw export --all > conversations-backup.json
# Backup configuration
cp ~/.openclaw/config.json ~/openclaw-config-backup.json
Make sure you have:
- [ ] API key (you'll reuse this with Hermes)
- [ ] List of installed skills
- [ ] Exported conversations (if you want to keep them)
- [ ] Configuration backup
- [ ] Any custom scripts or automations
Step 1: Install Hermes Agent
Install Hermes alongside OpenClaw β you don't need to uninstall OpenClaw first:
curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/install.sh | bash
Verify the installation:
hermes --version
# hermes-agent v0.8.x
Both tools can coexist with no conflicts. This lets you test Hermes before fully committing.
Step 2: Migrate Configuration
API Key
Your OpenRouter or OpenAI API key works with both tools:
# Get your API key from OpenClaw config
cat ~/.openclaw/config.json | grep api_key
# Set it in Hermes
hermes config set api_key "your-api-key-here"
Model Settings
OpenClaw and Hermes use slightly different model naming:
| OpenClaw Format | Hermes Format |
|----------------|---------------|
| claude-3-sonnet | anthropic/claude-3.5-sonnet |
| gpt-4 | openai/gpt-4o |
| llama-70b | meta-llama/llama-3.1-70b-instruct |
# Set your preferred model
hermes config set default_model anthropic/claude-3.5-sonnet
hermes config set provider openrouter
Behavior Settings
Map your OpenClaw preferences to Hermes:
# If OpenClaw had auto_execute: true
hermes config set auto_confirm true
# If OpenClaw had verbose: true
hermes config set verbose true
# Temperature
hermes config set temperature 0.7
Step 3: Migrate Conversations
Hermes includes a built-in migration tool for OpenClaw conversations:
# Migrate all conversations
hermes migrate openclaw --source ~/.openclaw/sessions
# Migrate specific sessions
hermes migrate openclaw --source ~/.openclaw/sessions/project-alpha
# Dry run (preview without changes)
hermes migrate openclaw --source ~/.openclaw/sessions --dry-run
Migration Preview:
Sessions found: 12
Total messages: 847
Destination: ~/.hermes/sessions/
β
project-alpha (142 messages)
β
web-scraper (89 messages)
β
daily-reports (203 messages)
β οΈ old-test (3 messages, skipping β too short)
...
Proceed? [y/N]
Manual Conversation Import
If the automatic migration doesn't work, you can import conversations manually:
# Export from OpenClaw
openclaw export --session project-alpha --format json > project-alpha.json
# Import into Hermes
hermes session import project-alpha.json
Step 4: Migrate Skills
Most OpenClaw skills have Hermes equivalents. Here's the mapping:
| OpenClaw Skill | Hermes Equivalent |
|---------------|-------------------|
| web-search | web-search (built-in) |
| file-reader | file-manager (built-in) |
| code-exec | code-runner (built-in) |
| github-tool | hermes skill install github-integration |
| email-sender | hermes skill install email-tool |
Install the equivalent skills:
# Install common skills
hermes skill install github-integration
hermes skill install email-tool
hermes skill install web-scraper
# List all available community skills
hermes skill search ""
Custom Skills
If you wrote custom OpenClaw skills, they need to be ported to Hermes format. The key differences:
// OpenClaw skill format (old)
module.exports = {
name: "my-skill",
execute: async (args, context) => {
return { result: "done" };
}
};
// Hermes skill format (new)
export default {
name: "my-skill",
version: "1.0.0",
description: "My custom skill",
parameters: {
input: { type: "string", required: true }
},
execute: async ({ input }, { agent, memory }) => {
return { success: true, output: "done" };
}
};
Key changes:
export default) instead of CommonJSversion and description fieldsparameters schemaexecute function receives destructured params and a richer context objectStep 5: Migrate Automations
If you used OpenClaw's scheduling (via external cron), Hermes has built-in support:
# Old approach: external crontab
# 0 9 * openclaw run "Generate daily report" --session daily
# New approach: Hermes built-in cron
hermes cron add "Generate daily report" --schedule "0 9 *" --session daily-reports
List and manage scheduled tasks:
hermes cron list
hermes cron enable daily-report
hermes cron disable daily-report
hermes cron delete daily-report
Step 6: Verify Everything Works
Run through this checklist to make sure the migration is complete:
# 1. Test connection
hermes --test-connection
# 2. Test a conversation
hermes "Hello! Tell me a joke."
# 3. Check migrated sessions
hermes session list
# 4. Verify skills
hermes skill list
# 5. Check memory
hermes memory list
# 6. Test cron (if used)
hermes cron list
Step 7: Decommission OpenClaw
Once you've verified everything works in Hermes, you can safely remove OpenClaw:
# Backup OpenClaw data (just in case)
tar -czf openclaw-backup.tar.gz ~/.openclaw
# Uninstall OpenClaw
npm uninstall -g openclaw
# Remove data directory (optional)
rm -rf ~/.openclaw
Tip: Keep the backup (
openclaw-backup.tar.gz) for at least a month, just in case you need to reference old conversations.
Troubleshooting Migration Issues
"Conversation format not recognized"
This usually means you're migrating from OpenClaw v1.x. Try:
hermes migrate openclaw --source ~/.openclaw/sessions --format v1
"Skill not compatible"
Some OpenClaw skills don't have direct Hermes equivalents. Check the community skills directory or port the skill manually.
"API key rejected"
If you were using OpenClaw's built-in API proxy, you'll need to get a direct API key from OpenRouter or your preferred provider.
