Documentation forServ-U File Server

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. Put the services in Disabled mode, and reboot the server.

    Rebooting the server ensures that any calls or dependencies the Serv-U services had on other resources do not affect the upgrade.

  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.
