# Move a Prepared Server to a Dark Site

# Move a Prepared Server to a Dark Site

A Mirror Server can be prepared and tested in an Internet-connected environment, then moved into the final dark-site network.

After the move:

1. boot the Mirror Server and configure its final dark-site IP address
2. open the GUI:

```bash theme={null}
sudo ubuntu-offline-mirror mirror-manager
```

3. open **Menu 1 — Configuration**
4. update the **Mirror Server IP** and save
5. run:

```text theme={null}
2  Download and Prepare Upgrade Files
3  Enable HTTP Distribution
4  Verify Upgrade Readiness
7  Show DP Client Upgrade Commands
```

6. confirm Menu 4 reports `PASS`
7. use only the newly generated Menu 7 commands

## Why Menu 2 is repeated

The current implementation reuses already prepared local artifacts where they remain valid, but it rebuilds client-side files that embed the Mirror Server IP.

Do not reuse commands generated before the IP change.

## Dark-site network requirement

Once the prepared server is in the restricted environment, DP hosts only need to reach:

```text theme={null}
http://<FINAL_MIRROR_SERVER_IP>:80
```

The DP hosts do not need direct Cloudflare R2 or ACPS access.
