In some situations, it may be necessary to make a clean install to make an upgrade work. You can do it by following steps below:
- Backup your host keys in etc directory (etc/ssh_host*)
- Uninstall the existing version of Copssh
- Remove remnants of the installation directory except home directories if they exist
- Make sure that the service account and the sshd account are removed if they exist
- Install new Copssh
- Restore host keys back to etc directory
- Start Copssh Control Panel and verify that the service is running
- Activate your users again and specify their existing home directories as the home directory during the activation
