Thanks Colin.
The conversion works. But then the problem shows, we have no network.
doing a urpmi --download-all --auto-update only downloads the fist 120+ rpms (the ones needed before 
restart-urpmi

What is needed is to add some directories and then the network will start
/var/run/netreport
/var/lock/subsystem/network

I will check after the upgrade if they can be deleted
