Overview

There are instances where reverting to a previous version after an upgrade is needed to isolate or troubleshoot an issue with the Serv-U MFT application.

Resolution

In preparation for the roll back:

Obtain a copy of the folders below from a current or previous Serv-U installation

C:\ProgramData\RhinoSoft\Serv-U (Folder is Hidden in Windows by default)
C:\Program Files\RhinoSoft\Serv-U
Linux - /usr/local/Serv-U

If using FTPS, HTTPS, or SFTP you will need to back up the additional key and cert files. The paths where these files are saved can be found in:

Serv-U Management Console > Go to Global > Limits & Settings . Encryption tab
Serv-U Management Console > Go to Domains > Limits & Settings . Encryption tab
- Any file ending with .crt
- Any file ending with .pem
- Any file ending with .key

Roll back procedure

1. Uninstall the Serv-U application

2. Install the previous version you wish to roll back to

Access the downloaded zip file for the installer and make sure to extract the contents.
Right-click the Serv-U MFT 15.4.x installer and select Properties.
Click "Unblock" if available.
Right-click the Serv-U MFT 15.4.x installer again, and then run the installer as an administrator.
Complete the installation wizard.

3. After completing the Serv-U installation, close the management console and stop the Serv-U service

4. Go to C:\ProgramData\RhinoSoft\Serv-U. Delete the Serv-U.Archive and Serv-U.Archive.Backup files

5. Copy the Serv-U.Archive file, Users folder, Shares folder (if any) and Serv-UID.txt file from your back up of ProgramData/Rhinosoft/Serv-U and paste them inside the current C:\ProgramData\RhinoSoft\Serv-U folder

5.b. If you are reverting back to an older version coming from version 15.3.2, edit the Serv-U.Archive first and remove the Server Identity entry. Remove the Server Identity information starting from the colon.
