  Hi!
 In one way, I very much appreciate the relatively high frequency of 
 updates done
by the XWIKI crew. You are doing a great job, making sure that
 XWIKI is alive and kicking and always improving.
 The downside to this, is all the work needed to be done when upgrading. 
 So, I
don't do that very often. The basic part of installation/migration
 works very well, but when it comes to content, the upgrade procedure is
 messy, as I see it. It is a hassle to have to pick and choose between
 various parts when importing and exported XAR.
 I would very much suggest planning for a future where the parts that are 
 XWIKI
software are clearly separated from the parts where customers
 typically do modifications. Especially items like users and groups. It
 should be possible to have a more separated export/import so that you GET
 new versions of e.g. the admin pages, while still KEEPING your setup of
 users, groups, etc., without having to click on a million of checkboxes in
 the import.
 I don't really understand this comment, doing export/import is really
 not the standard way of doing an upgrade. In typical upgrade you
 backup everything if you want to be safe (or better you have automated
 backups and you don't really need to do it when you upgrade), upgrade
 the WAR part (if you use the Debian package then it's just about doing
 apt-get upgrade or install with a specific version), restart, XWiki
 upgrade the database shema automatically if needed and then you get
 the Distribution Wizard which download and upgrade the wiki pages with
 3 ways merge. Most of the time you don't have anything to do.
 
 Sure, but to benefit from all those nice Distribution Wizard features,
 Harald would first need to... upgrade to the latest version ;-)
