How can I get rid of them? Uninstall + reinstall won't help.
In order to avoid that, the add-on product needs to provide an
update/migration step. That's because sometimes there are some incompatible
changes from another versions. Most of the add-ons don't need that, or the
developer hasn't written one yet.

So, a workaround is to go to the ZMI -> Portal QuickInstaller  and select
the product you want to upgrade. Always try this with a backup of your ZODB
in case something goes wrong.

Maybe others on this list can give some more information about the Kupu
add-on on Plone 4.x

> What I did was as follows:
> - Install plone 4 via the installer
> - Copy the data.fs to the new plone installation
> - Update / change buildout.cfg as in previous version and run buildout
> - Start plone
> Thanks for any hints,
