Upgrade Serv-U File Server

Before you upgrade or migrate the Serv-U File Server, you should back up the server definition (that is, the Serv-U configuration files and directories listed below). Only Serv-U Local Administrators or full privileged System Administrators can export these files.

Copying the files from the source server can be done while the Serv-U server is live with no data integrity issues. However, when you restore the configuration files to a new server (or rebuild 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.

For more information about backing up, restoring, or migrating Serv-U, see Back up or move Serv-U settings.

Back up files on a Windows server

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 files 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 Management Console to see if these files are being stored elsewhere.

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.

Back up files on a Linux server

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


When installing Serv-U 15.3.2 or later over an existing version of Serv-U, you will be asked if you want to create or import an existing Server Identifier. If you are upgrading a single instance of your server, you should create a server identifier. If you are upgrading a multi-tier set of Serv-U instances, see set up a new multi-tier Serv-U Server across multiple machines.

  1. Back up your old Serv-U settings as described above. If you have version 15.3.2 or later, you should also export the Server Identifier.

  2. Download the latest licensed version of Serv-U from the Customer Portal, and save it to a temporary directory.

  3. Stop the Serv-U services.

  4. Open the file, and run the program as administrator.

  5. When prompted, overwrite the existing version.

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

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

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