OK, I would install a newer version then, which one do

me to install?
Do I have to uninstall the old one or just make an update?
The latest stable version 1.2.1 should be fine. Look at the migration notes in
the wiki for update hints,

As you going from 1.0 to 1.2, a complete new installation would be probably
easier. So uninstall the old openser, backup your database tables, install
the new and migrate the data to the new installation. You find informations
about the necessary changes in the mentioned documents.
