Test Environment

Agent ID: 2392dd78-70cf-49f7-b40e-673cf3afb944
Previous Version: 0.1.23
New Version: 0.1.23.5
Platform: Fedora Linux
Migration Path: In-place binary upgrade

Migration Results

✅ SUCCESSFUL MIGRATION

1. Agent Version Update

Agent successfully updated from v0.1.23 to v0.1.23.5
No re-registration required
Agent ID preserved: 2392dd78-70cf-49f7-b40e-673cf3afb944

2. Token Preservation

Access token automatically renewed using refresh token
Agent ID maintained during token renewal: "✅ Access token renewed successfully - agent ID maintained: 2392dddd78-70cf-49f7-b40e-673cf3afb944"
No credential loss during migration

3. Configuration Migration

Config version updated successfully
Server configuration sync working: "📡 Server config update detected (version: 1762959150)"
Subsystem configurations applied:
- storage: 15 minutes
- system: 30 minutes → 5 minutes (after heartbeat)
- updates: 15 minutes

4. Heartbeat/Rapid Polling

Heartbeat enable command received and processed successfully
Rapid polling activated for 30 minutes
Immediate check-in sent to update server status
Pending acknowledgments tracked and confirmed

5. Command Acknowledgment System

Command acknowledgments working correctly
Pending acknowledgments persisted across restarts
Server confirmed receipt: "Server acknowledged 1 command result(s)"

Issues Identified

🔍 Potential Issue: Scanner Interval Application

Observation: User changed "all agent_scanners toggles to 5 minutes" on server, but logs show different intervals being applied:

storage: 15 minutes
system: 30 minutes → 5 minutes (after heartbeat)
updates: 15 minutes

Expected: All scanners should be 5 minutes

Possible Causes:

Server not sending 5-minute intervals for all subsystems
Agent not correctly applying intervals from server config
Only "system" subsystem responding to interval changes

Investigation Needed:

Check server-side agent scanner configuration
Verify all subsystem intervals in server database
Review syncServerConfig function in agent main.go

Conclusion

Migration Status: ✅ SUCCESSFUL

The migration from v0.1.23 to v0.1.23.5 worked perfectly:

Tokens preserved
Agent ID maintained
Configuration migrated
Heartbeat system functional
Command acknowledgment working

Remaining Issue: Scanner interval configuration may not be applying uniformly across all subsystems. Requires investigation of server-side scanner settings and agent config sync logic.
