Hi,

I'm running a pretty old version, 1.3.9, and would like to upgrade to
the most current version, 1.6.6 as of now.

I'm not yet sure, but as it seems I've to do the upgrade in steps:

* upgraed to 1.4
* upgrade to 1.5
* finally upgrade to 1.6.6

Is this true or can I immidiately upgrade to 1.6.6?

For us only the articles/categories are really important. Users, etc.
are not relevant for us. We don't use any advanced stuff like templates
or similiar things and there are just some few uploads.

Is there another way to export all the MediaWiki content to a neutral
format which can be important into the latest version?

thanks,
- - Markus
