 I generally move directly between major
 versions as soon as convenient. The factor that has the most bearing on
 when we upgrade is the ease with which we can move between new versions.

 I remember seeing an items relating to simpler installation. I'd like to
 ask when that is scheduled to be worked on, and perhaps share some of my
 experiences in upgrading and some suggestions.


A part of it (related to import) is being worked on right now. The work on a
full-fledged Extension Manager has not started yet.

I'd like to give you an idea of what has to be done to move between
 versions. It's a bit long, so bear with me, but here it is:

 * Download the latest xwiki xar to your local machine
 * Download the latest xwiki war to the machine which will run xwiki.
 * Backup the entire xwiki installation directory (the one that contains
 the directories database, jetty, lucene etc), and move the old directory
 aside (rename to xwiki.old)
 * //We do this to easily be able to get the jetty, hsql, etc dirs back
 in place//: Restore the backed up xwiki directory, thus putting the
 xwiki dir back in place
 * Delete the directory xwiki/webapps/xwiki
 * In xwiki/webapps, create an xwiki directory
 * Unzip the xwiki war in the xwiki/webapps/xwiki directory
 * //Getting our corp logo back//: Copy
 xwiki.old/webapps/xwiki/skins/toucan/mywiki.jpg to
 xwiki/webapps/xwiki/skins/toucan/mywiki.jpg
 * //Next few steps: need to merge old config with new config//: Do a
 diff between xwiki.old/webapps/xwiki/WEB-INF/xwiki.cfg and
 xwiki/webapps/xwiki/WEB-INF/xwiki.cfg. Update
 xwiki/webapps/xwiki/WEB-INF/xwiki.cfg as needed.
 * Do a diff between xwiki.old/webapps/xwiki/WEB-INF/xwiki.properties and
 xwiki/webapps/xwiki/WEB-INF/xwiki.properties. Update
 xwiki/webapps/xwiki/WEB-INF/xwiki.properties as needed.
 * Do a diff between xwiki.old/webapps/xwiki/WEB-INF/hibernate.cfg.xml
 and xwiki/webapps/xwiki/WEB-INF/hibernate.cfg.xml. Update
 xwiki/webapps/xwiki/WEB-INF/hibernate.cfg.xml as needed.
 * //This is the part we fear the most, for we might accidentally delete
 some configuration that we need and we would need to start the whole
 process again//: Start XWiki and import the default wiki xar. Be careful
 of what you import - read the instructions at

 http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Installation#HUpgradingwikidocuments
 .
 ** The normally excluded pages from import are:
 *** XWiki.XWikiPreferences
 *** XWiki.XWikiGroups
 *** XWiki.XWikiAdminGroup
 *** XWiki.WebPreferences
 *** XWiki.WebHome
 *** XWiki.XWikiUsers
 *** XWiki.XWikiAllGroup
 *** XWiki.DefaultSkin
 *** Main.WebHome
 *** Panels.QuickLinks
 *** Panels.Search
 * //We customise the PDF cover//: The PDF covers files has been manually
 modified. Do a diff between
 xwiki.old/webapps/xwiki/templates/pdfcover.vm and
 xwiki/webapps/xwiki/templates/pdfcover.vm. Merge the differences.

 modified by hand. Do a diff between
 xwiki.old/webapps/xwiki/templates/pdffooter.vm and
 xwiki/webapps/xwiki/templates/pdffooter.vm. Merge the differences.
 * //We do this to be able to specify the PDF template to use in Export

 exported using the correct stylesheet. Do a diff between
 xwiki.old/webapps/xwiki/templates/menuview.vm and
 xwiki/webapps/xwiki/templates/menuview.vm. Merge the differences (there
 should only be one line).As you can see, there are quite a few steps,
 and it normally takes 1/2hr - 1hr to complete. Note that we will move to
 MySQL eventually, but the performance of HSQL is OK ATM.


Thanks for the feedback.

This may not be the most optimal upgrade path, so if there are any clear
 improvements you can see, please let me know.

 The part that needs to be improved upon the most, in my opinion, is the
 import default XAR step because it is easy to overwrite an important
 page. I would like to put in a big vote for separating information that
 can be modified by the user from information that xwiki needs to be able
 to operate, that comes with default xwiki. Perhaps making certain pages
 system pages so that it is clear that if a page is modified it may
 interrupt the operation of the wiki, and may be difficult to upgrade.


Definitely. This is the most dangerous part and it has triggered manny
mistakes in the past. One of the XWiki developers is currently working on a
patch that will improve the way the import works: imported pages will add a
version to existing pages instead of overriding them. He should be able to
commit his patch in the 2.1 timeframe.

About marking system pages, that has been started a bit too - you'll
notive that in the default XAR some pages are marked as having been modified
