Upgrade Serv-U File Server

Before you upgrade or migrate the Serv-U File Server, you should back up the Serv-U configuration files and directories listed below.

The C:\ProgramData directory may be hidden on your PC. To show it, select the View tab in File Explorer and select Hidden files.


Directories Files







C:\ProgramData\RhinoSoft\Serv-U\Users\domain-name username.Archive
C:\Program Files\RhinoSoft\Serv-U

Any files with the .crt, .pem and .key extensions

These file are stored by default in your installation directory, but you should check the Domain Limits & Settings > Encryption (for each domain) tabs and Server Limits & Settings> Encryption tab in the Managment Console to see if these files are being stored elsewhere.

Copying the files from the source server can be done while the Serv-U server is live with no data integrity issues. However, when restoring the configuration files to a new server (or rebuilding an existing server) the Serv-U service must be stopped while the files are imported. To stop the Serv-U service, right click on the Serv-U Tray and select Serv-U.

It is a best practice to store these all in one directory for the server or in one directory per domain so they are convenient for backing up.


If running Serv-U under Linux, the above files will be found in the /usr/local/Serv-u directory.


  1. Back up your old Serv-U settings as described above.
  2. Download the latest licensed version of Serv-U from the Customer Portal, and save it to a temporary directory.
  3. Open the file, and run the program as administrator.
  4. When prompted, overwrite the existing version.

    The latest version will be installed on top of the current version of your Serv-U.

  5. Apply any hotfixes for the current version if available.

    If you experience issues with the Management Console after upgrading, clear your browser cache.
