recent version is 1.8

Please follow the guidance in your docs dir e.g.

Since 1.5.3 we provide one single migration command.

If your moin instance is older and you never had called any migration
script please read carefully README.migration and call the older
migration methods.

please completely read it until you reach the version
you were using until now - otherwise you might miss
some important upgrading and configuration hints.
Starting with 1.5.3, update installation hints are
marked with HINT. They assume you are upgrading from

I don't know currently which modifications at all were done by your
distribution, why they don't tell you that you have to invoke moin ...
migration data for your existing instance or why they didn't.
