Server Migration

Desktop App only

Server migration applies to the DPD Label Print desktop application installed on a server.

Move an existing DPD Label Print installation from one server to another — for example when replacing hardware or moving to a new machine — while keeping all your data (shipment history, settings, users and database).

All application data lives in the data folder you selected during installation (by default C:\ProgramData\DPD\LabelPrintClient). Migration works by copying that folder from the old server to the new one.

Before you begin​

  • Make sure you can log in to the old server and locate its data folder (default: C:\ProgramData\DPD\LabelPrintClient).
  • Install the same or a higher version of DPD Label Print on the new server. Never install a lower version, as it may not be compatible with the migrated database.
  • Have your login credentials ready — they are unchanged after migration.
Stop before copying

Copy the data folder only while the application is stopped on both servers. Copying a running instance's database can result in corrupted or incomplete data.

Migration steps​

1. Install DPD Label Print on the new server​

Run the installer on the new server and complete the setup as described in Installation (or Server Installation for a shared, service-based deployment). Note the data folder path you enter during installation.

2. Stop the application​

Stop DPD Label Print on the new server so no process is using the data folder.

  • For a desktop installation: close the launcher window.
  • For a Windows service installation: open the Services console (services.msc), find DPD Label Print Service, right-click it and choose Stop.

Also stop the application on the old server so its data folder is in a consistent state before copying.

3. Replace the data folder​

Replace the new server's data folder — the one you entered during installation (usually C:\ProgramData\DPD\LabelPrintClient) — with the contents of the same folder from the old server.

  1. On the old server, copy the entire data folder (C:\ProgramData\DPD\LabelPrintClient).
  2. On the new server, delete or back up the freshly created data folder.
  3. Paste the old server's folder in its place, keeping the same path.
tip

If you configured a custom data folder location during installation, use that path instead of the default.

4. Start the application​

Start DPD Label Print on the new server.

  • For a desktop installation: launch it from the Start menu or desktop shortcut.
  • For a Windows service installation: open the Services console (services.msc), find DPD Label Print Service, right-click it and choose Start.

5. Log in and verify​

Open the application in your browser and log in with the same credentials you used on the old server. Verify that your data was migrated correctly:

  • Shipment history is present
  • Settings and printer configuration are unchanged
  • User accounts still work
  • Customer / product configuration is intact

After migration​

  • Keep the old server (or a backup of its data folder) until you have confirmed everything works on the new server.
  • Once verified, decommission the old server to avoid two instances running against the same account.
