Breaking Changes
Config file format change
auto-migratedopenclaw.config.json β openclaw.config.yaml. The migration tool converts this automatically, but custom scripts that read the config file may need updating.
Memory database schema
auto-migratedThe single SQLite database is split into three layers. Existing data is migrated to the 'warm' layer during upgrade.
Plugin SDK v1 deprecation
compatible with warningsSDK v1 plugins still work via the compatibility layer but show deprecation warnings. Plan to update to SDK v2 within 6 months.
Node.js version requirement
manual action requiredv2026 requires Node.js 20+ (v2025 supported Node 18+). Update Node.js before upgrading.
Docker base image change
manual action requiredThe Docker image switched from node:18-alpine to node:20-slim for better compatibility. Update your docker-compose.yml image tag.
Step-by-Step Migration
# Step 1: Backup everything openclaw backup --full --output ~/openclaw-v2025-backup.tar.gz # Step 2: Check prerequisites node --version # Must be 20.x+ docker --version # Must be 24.x+ (if using Docker) # Step 3: Update Node.js if needed brew install node@20 # macOS # or: nvm install 20 # NVM users # Step 4: Run the migration tool openclaw update --from v2025 --to v2026 # This will: # β Convert config from JSON to YAML # β Migrate memory database to 3-tier format # β Update plugin manifests to SDK v2 compat # β Create rollback point # Step 5: Verify openclaw doctor openclaw status # Step 6: (Optional) Rollback if issues openclaw rollback # Restores v2025 within seconds
Post-Migration Checklist
Frequently Asked Questions
Will I lose my agent's memory during upgrade?
No. The migration tool automatically converts your v2025 memory database to the new v2026 3-tier format (hot/warm/cold). Always backup your /data directory before upgrading as a safety precaution.
How long does the migration take?
The actual upgrade takes 5-10 minutes. The memory migration runs in the background and completes within 30-60 minutes depending on database size.
Can I roll back to v2025 if something breaks?
Yes. The migration tool creates an automatic backup. Run 'openclaw rollback' to restore the previous version. Rollback is supported for 30 days after upgrade.
Are v2025 plugins compatible with v2026?
Most plugins work without changes. The Plugin SDK v1 compatibility layer handles 90% of cases. Plugins using deprecated APIs will show warnings and should be updated to SDK v2.
