# Step 6: Synology Transition (~2 hours, remote)

---

## 6.1 — Verify drive mappings

On each machine via ScreenConnect:

```powershell
net use
```

Confirm mapped drives (S:, department drives) point to `\\CS-SERVER\...` and files are accessible.

**Do not proceed until all users have working drive mappings.**

---

## 6.2 — Remove Synology Drive Client

On each machine via ScreenConnect:

1. Right-click Synology Drive Client in system tray → Quit
2. Settings → Apps → Synology Drive Client → Uninstall
3. Verify user can access files via mapped drives (not Synology)

Or via PowerShell:
```powershell
# Find and uninstall Synology Drive Client
$synology = Get-WmiObject Win32_Product | Where-Object { $_.Name -like "*Synology Drive*" }
if ($synology) {
    $synology.Uninstall()
    Write-Host "Synology Drive Client uninstalled"
} else {
    Write-Host "Synology Drive Client not found"
}
```

---

## 6.3 — Disable Synology Drive Server sync

1. Log into Synology DSM at `https://192.168.0.120:5001`
2. Open Synology Drive Admin Console
3. Disable all sync tasks
4. Optionally disable Synology Drive Server package (don't uninstall yet)

---

## 6.4 — Repurpose Synology as backup-only

1. Verify Active Backup for Business is backing up CS-SERVER nightly (set up in Step 1)
2. Configure offsite backup:
   - Install **Hyper Backup** from Package Center
   - Create task → Backblaze B2 or Wasabi (~$3/mo for offsite copy)
   - Schedule: daily after ABB completes (e.g., 5:00 AM)
   - Retention: 30 daily + 12 monthly

---

## 6.5 — Archive SynologyDrive folder

Run `scripts/phase4-archive-synology.ps1` on CS-SERVER:

```powershell
Rename-Item "D:\Shares\SynologyDrive" "D:\Shares\_SynologyDrive_ARCHIVE_DeleteAfter30Days"
```

**Do NOT delete immediately** — keep 30 days as safety net. Set a calendar reminder to delete after 30 days.

---

## Rollback

- Rename archive folder back: `Rename-Item "D:\Shares\_SynologyDrive_ARCHIVE_DeleteAfter30Days" "D:\Shares\SynologyDrive"`
- Re-enable Synology Drive Server sync
- Reinstall Synology Drive Client on workstations
