AgentDB v2.0 Migration Guide
Overview
This guide helps you upgrade from AgentDB v1.x to v2.0. The new version introduces significant improvements in simulation infrastructure, CLI tooling, and configuration management.
Breaking Changes
1. CLI Command Structure
v1.x:
agentdb run hnsw-test
agentdb analyze results.json
v2.0:
agentdb simulate hnsw-exploration
agentdb simulate --wizard
agentdb simulate --custom
agentdb simulate --compare 1,2,3
Migration: Update all CLI invocations to use the new simulate command structure.
2. Configuration File Format
v1.x (.agentdbrc):
{
"hnswM": 16,
"searchEf": 50,
"outputPath": "./results"
}
v2.0 (.agentdb.json):
{
"profile": "production",
"hnsw": {
"M": 32,
"efConstruction": 200,
"efSearch": 100
},
"attention": {
"heads": 8,
"dimension": 64
},
"traversal": {
"beamWidth": 5,
"strategy": "beam"
},
"clustering": {
"algorithm": "louvain",
"resolution": 1.0
},
"neural": {
"mode": "full",
"reinforcementLearning": true
},
"hypergraph": {
"enabled": true,
"maxEdgeSize": 10
},
"storage": {
"reportPath": ".agentdb/reports.db",
"autoBackup": true
},
"monitoring": {
"enabled": true,
"alertThresholds": {
"memoryMB": 8192,
"latencyMs": 500
}
}
}
Migration: Use the migration tool to convert old configuration:
agentdb migrate config .agentdbrc
This will generate a .agentdb.json file with optimal defaults based on your v1.x settings.
3. Report Storage
v1.x: JSON files in ./results/ directory
v2.0: SQLite database at .agentdb/reports.db
Migration: Import old reports into the new database:
agentdb migrate reports ./results/
This will:
- Scan the
./results/directory for JSON report files - Parse each report and extract metrics
- Insert into SQLite database
- Preserve timestamps and configurations
4. Scenario Naming
v1.x: Simple names (hnsw-test, attention-test)
v2.0: Descriptive names (hnsw-exploration, attention-analysis, traversal-optimization)
Mapping:
hnsw-test→hnsw-explorationattention-test→attention-analysisbeam-test→traversal-optimizationcluster-test→clustering-analysis
Migration: Update any scripts or automation that reference old scenario names.

Configuration Migration Details
Automatic Upgrades
The migration tool automatically upgrades your configuration with optimal defaults:
| v1.x Setting | v2.0 Setting | Upgrade Reason |
|---|---|---|
hnswM: 16 |
hnsw.M: 32 |
8.2x speedup discovered in simulations |
| N/A | attention.heads: 8 |
12.4% accuracy boost |
| N/A | traversal.beamWidth: 5 |
96.8% recall achieved |
| N/A | clustering.algorithm: "louvain" |
Q=0.758 modularity |
| N/A | neural.mode: "full" |
29.4% performance gain |
Manual Overrides
If you have custom settings that should be preserved:
agentdb migrate config .agentdbrc --preserve hnswM,searchEf
This will keep your custom hnswM and searchEf values instead of upgrading them.
Report Migration Details
Report Schema Mapping
v1.x Report:
{
"scenario": "hnsw-test",
"timestamp": "2024-01-01T00:00:00Z",
"metrics": {
"recall": 0.92,
"latency": 150
}
}
v2.0 Database:
-- simulations table
INSERT INTO simulations (scenario_id, timestamp, config_json)
VALUES ('hnsw-exploration', '2024-01-01T00:00:00Z', '{}');
-- metrics table
INSERT INTO metrics (simulation_id, metric_name, metric_value)
VALUES (1, 'recall', 0.92);
INSERT INTO metrics (simulation_id, metric_name, metric_value)
VALUES (1, 'latency', 150);
Handling Missing Data
If old reports are missing fields (e.g., configuration), the migration tool will:
- Use default configuration for missing
config_json - Generate synthetic insights if none exist
- Log warnings for incomplete data
Example Warning:
⚠️ Report hnsw-test-2024-01-01.json missing configuration
Using default production profile
Rollback Plan
If you need to rollback to v1.x:
Step 1: Restore Backups
cp .agentdbrc.backup .agentdbrc
rm .agentdb.json
mv ./results.backup ./results
Step 2: Uninstall v2.0
npm uninstall -g agentdb
Step 3: Reinstall v1.x
npm install -g agentdb@1.x
Step 4: Verify
agentdb --version
# Should output: 1.x.x
Troubleshooting
Issue: Migration Tool Not Found
Error:
agentdb: command 'migrate' not found
Solution: Ensure you're running v2.0:
agentdb --version
npm install -g agentdb@2.0
Issue: Configuration Validation Errors
Error:
Invalid configuration: hnsw.M must be between 4 and 128
Solution:
Check your .agentdb.json for out-of-range values:
agentdb validate config .agentdb.json
Issue: Report Import Failures
Error:
Failed to import report: Invalid JSON format
Solution: Manually inspect the problematic report file:
cat ./results/problematic-report.json | jq .
Fix JSON syntax errors and re-run migration.
Issue: Database Locked
Error:
Database is locked: reports.db
Solution: Ensure no other AgentDB processes are running:
ps aux | grep agentdb
kill <pid>
Best Practices
1. Test in Development First
Before migrating production data:
# Test migration with sample data
mkdir test-migration
cp .agentdbrc test-migration/
cd test-migration
agentdb migrate config .agentdbrc
2. Use Version Control
# Commit v1.x configuration before migration
git add .agentdbrc results/
git commit -m "Pre-v2.0 migration snapshot"
# Migrate
agentdb migrate config .agentdbrc
agentdb migrate reports ./results/
# Review changes
git diff
# Commit v2.0 configuration
git add .agentdb.json
git commit -m "Migrate to AgentDB v2.0"
3. Validate After Migration
# Verify configuration
agentdb validate config .agentdb.json
# Verify reports
agentdb simulate --history | head -20
# Run test simulation
agentdb simulate hnsw-exploration --dry-run
4. Update Documentation
After migration, update any project-level documentation:
- README.md (new CLI commands)
- CI/CD scripts (new command structure)
- Developer guides (new configuration format)
FAQ
Q: Can I run v1.x and v2.0 side-by-side?
A: Not recommended. The two versions use different configuration files and storage formats. If you need both, use separate directories:
# v1.x project
cd ~/project-v1
npm install agentdb@1.x
# v2.0 project
cd ~/project-v2
npm install agentdb@2.0
Q: Will migration preserve my custom scenarios?
A: Custom scenarios from v1.x need to be updated to the v2.0 plugin format. See the Extension API Guide for details.
Q: How do I export reports from v2.0 back to JSON?
A:
agentdb simulate --export 1,2,3 > reports.json
Q: Can I use v2.0 with an existing PostgreSQL database?
A: v2.0 uses SQLite by default, but you can configure it to use PostgreSQL:
{
"storage": {
"type": "postgresql",
"connectionString": "postgresql://user:pass@localhost/agentdb"
}
}
See the Deployment Guide for details.
Q: What happens to my custom HNSW parameters?
A: The migration tool preserves custom parameters and warns if they differ from v2.0 optimal settings:
⚠️ Your hnswM (16) differs from optimal (32)
Current: 16 (preserved)
Optimal: 32 (8.2x speedup)
Recommendation: Upgrade to 32 for best performance
