CS-SERVER post-reboot verification: time sync, TLS 1.2 enforcement, and Windows Server Backup feature all persisted cleanly. dcdiag clean. Ready for Entra Connect install. Synology cascadesDS permission inventory captured via DSM API (SSH disabled by default on Synology). 35 users, 4 groups, 10 shares. Analysis identifies 7 shared-account role logins (HIPAA violation), 8 departed-employee accounts to clean up, and 4 shares needing Meredith-side confirmation before migration (pacs most sensitive).

Cascades Network Migration — Revised Operational Plan
Context
Cascades senior living facility (236 rooms, 6 floors). New MSP takeover from previous company that left environment non-compliant. Core mission: HIPAA remediation and compliance. Synology NAS stores PHI, nurses/medtechs access clinical records via ALIS (cloud), and email may contain resident data. See security/hipaa.md for full gap analysis.
Single 16-year-old server (CS-SERVER, 192.168.2.254) on LAN (192.168.0.0/22) running all roles. Staff PCs currently on WiFi (INTERNAL VLAN 20, 10.0.20.0/24). Printers on LAN. No backups, no GPOs, wide-open firewall, 4 PCs not domain-joined.
Revised approach: Network first. Move all devices to INTERNAL VLAN 20, then lock down. Server and printers move to INTERNAL last — no disruption during transition.
Transitional state: Machines on INTERNAL (10.0.20.0/24) → pfSense firewall bridges → CS-SERVER + printers on LAN (192.168.0.0/22). Everything works cross-subnet until we move the server.
HIPAA drives every phase: Backup (Phase 0) → network isolation (Phase 1) → access control + encryption (Phase 2) → centralized management (Phase 3) → PHI migration with audit trails (Phase 4) → shared account elimination (Phase 5).
Schedule
| Session | Steps | Est. Time | Impact |
|---|---|---|---|
| Session 1 (evening) | 1 + 2 | ~3-4 hours | Backup + firewall changes during low usage |
| Session 2 (coordinated) | 3 | ~2-3 hours | Brief disruption per machine during port change |
| Session 3 (business hours) | 4 | ~4-6 hours | No user impact — server-side only |
| Session 4 (coordinated) | 5 | ~4-6 hours | Brief disruption per machine during domain join |
| Session 5 (business hours) | 6 + 8 | ~4-5 hours | Synology cutover + hardening |
| Session 6 (TBD) | 7 | ~3-4 hours | Server/printer IP changes — schedule when stable |
Total: ~20-28 hours across 6 sessions

On-Site Tasks (separate trip)
| Task | Why |
|---|---|
| Fix 9 offline APs | Physical access to check PoE, cables, re-adopt |
| Wire 206 printer (ethernet) | Cable run |
| Locate Bizhub C368 | Physical walkthrough |
| Get printer MAC addresses | If not in pfSense ARP/DHCP table |
| Verify switch port assignments | Physical trace if UniFi doesn't show clearly |
Information Still Needed
- Switch port mappings — Which switch port is each hardwired workstation plugged into? Check UniFi → Clients or trace physically. Only CHEF-PC (USW Lite 8 Port 7) is known.
- DESKTOP-1ISF081 IP and location — What IP does it have and where is it physically?
- MDIRECTOR-PC — Confirm it should move to INTERNAL or stay on LAN (MemCare Director's machine, currently at 192.168.3.20)
- Printer MAC addresses — Need for DHCP reservations if not already in pfSense ARP table
- Step 7 decision — Move CS-SERVER to INTERNAL, dual-home it, or leave on LAN permanently?
Rollback Procedures
Each step has a rollback section. Key rollbacks:
- Step 2: Re-enable floating rule #4, revert Guest SSID, restore pfSense XML backup
- Step 3 (per machine): Revert switch port to native VLAN
- Step 4: Unlink GPOs from GPMC. DNS records exported in Step 1.
- Step 5 (per machine): Log in with MSPAdmin local account,
Remove-Computer -UnjoinDomainCredential (Get-Credential) -Restart - Step 6: Rename archive folder back to SynologyDrive
- Step 7: Revert printer/server IPs, restore firewall rules
Verification
After each step, confirm:
- Step 2: INTERNAL machines can reach server + printers through firewall
- Step 3: Hardwired machines on INTERNAL get correct IPs, reach server + printers
- Step 4: All shares/groups/GPOs created correctly on CS-SERVER
- Step 5: Domain-joined machines get GPOs, drive mappings, printers automatically
- Step 6: Users can access all files via mapped drives (no more Synology Drive Client)
- Step 7: Server/printers accessible on new IPs from all machines
- Step 8: Endpoint security deployed, old accounts/shares cleaned up
