Upgrade non roaming user settings to roaming in Net 2.0

Question

We have a .NET 2.0 application out where we've set the user settings Roaming = False (the default value).

Now, some citrix users complain that the settings are not stored. We belive the problem will be solved by setting Roaming = True.

But how do we update the application at the clients and at the same time restore previously stored settings. Normally this is done by calling My.Settings.Upgrade(), but I guess this will not work in this case when settings are changed from Roaming = False to Roaming = True.

Any thoughts, anyone?
