Automatic uninstallation but keeping userdata

Hi,

I want to uninstall WinSCP 5.1.7 silent and automatically but also want to keep the winscp-userdata. So I can install WinSCP 5.5.3 silent and automatically and the user has is old data from the old version.
Just installing the new version is not an option so far because the default install path is changing (on my computers) between these two versions.

Thanks Sascha

Use unins000.exe /silent. Configuration won't be removed.
