Last Updated: 2025-11-25 Current Phase: Phase 2 COMPLETE, Phase 3 PLANNED

---

Migration Status

Phase	Status	Description	Completed
Phase 1	COMPLETE	Schema changes (tables, columns, indexes)	Nov 6, 2025
Phase 2	COMPLETE	PC migration to machines table	Nov 10, 2025
Phase 3	COMPLETE	Network devices - legacy tables dropped	Nov 25, 2025

Phase 1: Schema Changes (COMPLETE)

Completed: November 6, 2025

New Tables Created (7)

1. comstypes - Communication types (IP, Serial, etc.)
2. communications - Unified network interfaces
3. warranties - Warranty tracking
4. compliance - Compliance tracking
5. compliancescans - Scan history
6. relationshiptypes - Relationship type definitions
7. machinerelationships - Machine-to-machine relationships

Tables Modified (2)

1. machines - Added 11 columns (hostname, serialnumber, osid, pctypeid, etc.)
2. businessunits - Added liaison fields

Tables Renamed

• pcstatus → machinestatus

---

Phase 2: PC Migration (COMPLETE)

Completed: November 10, 2025

Data Migrated

• 277 PCs migrated from pc table → machines table
• 705+ network interfaces → communications table
• Dualpath relationships → machinerelationships table
• PC→Equipment relationships → machinerelationships table

Schema Changes

• PCs identified by pctypeid IS NOT NULL in machines table
• Network interfaces use communications.address field
• Relationships use machinerelationships table

Pages Updated

• displaypcs.asp, displaypc.asp, editpc.asp
• displaymachines.asp, displaymachine.asp
• network_map.asp, network_devices.asp
• All save/update device pages

API Fixes

• Fixed 36+ IIf() bugs in api.asp
• Fixed PC→Machine relationship creation
• PowerShell data collection fully working

---

Phase 3: Network Devices (COMPLETE)

Completed: November 25, 2025

What Happened

• Legacy tables were essentially empty (only 3 servers had data)
• Network devices were already being added directly to machines table
• Dropped all legacy network device tables

Tables Dropped

• servers (3 records - not migrated, stale data)
• switches (empty)
• cameras (empty)
• accesspoints (empty)
• idfs (empty)

Current Network Device Types in machines Table

machinetypeid	Type
16	Access Point
17	IDF
18	Camera
19	Switch
20	Server

Printers

• Stay in separate printers table (by design - unique fields, workflows)

---

Current Architecture

machines table (unified)
├── Equipment (machinetypeid 1-24, pctypeid IS NULL)
├── PCs (machinetypeid 25-29, pctypeid IS NOT NULL)
└── [Future] Network Devices (machinetypeid 30-36)

printers table (separate)

communications table (all network interfaces)

machinerelationships table (all relationships)

---

Key Queries

-- All PCs
SELECT * FROM machines WHERE pctypeid IS NOT NULL;

-- All Equipment (non-PC)
SELECT * FROM machines WHERE pctypeid IS NULL;

-- PCs with network info
SELECT m.hostname, m.serialnumber, c.address
FROM machines m
LEFT JOIN communications c ON m.machineid = c.machineid
WHERE m.pctypeid IS NOT NULL;

-- PC → Equipment relationships
SELECT
    pc.hostname AS pc_name,
    eq.machinenumber AS equipment_name
FROM machinerelationships mr
JOIN machines pc ON mr.machineid = pc.machineid
JOIN machines eq ON mr.related_machineid = eq.machineid
JOIN relationshiptypes rt ON mr.relationshiptypeid = rt.relationshiptypeid
WHERE rt.relationshiptype = 'Controls';

---

Deprecated Tables (Phase 2)

These tables are deprecated but kept for rollback safety:

• pc → Use machines WHERE pctypeid IS NOT NULL
• pc_network_interfaces → Use communications
• pc_comm_config → Use communications
• pc_dualpath_assignments → Use machinerelationships
• pcstatus → Use machinestatus

Recommendation: Drop after 30 days of stable operation
