Hi guys, Tried migrating from 3.5 to 4.1.3 on my test instance, and it seems I'm stuck ... My test wiki is setup as a multi-wiki environment (for workspaces), the main db "xwiki" fails to be migrated, though other ones succeed. I checked other posts about migration issues, and it seems there usually are some indicative logs about what sql fails, in my case I only get a not nice NPE ... I saw other things about custom annotation class, but I do not remember having customized this in any way ... Some residue of previous migrations maybe ? The error in logs at startup is : 2012-08-06 14:06:58,920 [http://hostname:8080/xwikitest/bin/view/Main/] INFO .HibernateDataMigrationManager - Running storage schema updates and migrations 2012-08-06 14:06:59,110 [http://hostname:8080/xwikitest/bin/view/Main/] INFO .HibernateDataMigrationManager - Starting migration for database [xwiki]... 2012-08-06 14:06:59,527 [http://hostname:8080/xwikitest/bin/view/Main/] WARN h.R40001XWIKI7540DataMigration - Skipping database [xwiki] because it uses a custom annotation class.

Just a followup on this one, so anyone falling here knows the outcome. The related JIRA issues are: XWIKI-8126: Better error reporting when proper hibernate mapping is not found during R40000XWIKI6990. XWIKI-8130: copyDocument should not copy the custom mapping of the document xClass The NPE exception will be replace by an DataMigrationException with a message similar to the following in our next releases (4.1.4 and 4.2M3): Could not migrate IDs for class [XWiki.CopyOfXWikiPreferences] : no The problem encountered by Jeremie is that he have made a copy of XWiki.XWikiPreferences into a new document XWiki.CopyOfXWikiPreferences. That new document will contains the preferences in an object of class XWiki.XWikiPreferences, but it will also define a new class named XWiki.CopyOfXWikiPreferences which is the copy of the class XWiki.XWikiPreference. That new class received the same internal mapping than its original source. However, the hibernate mapping needed is not available in the hibernate mapping configuration, and that new class is unusable and cannot be migrated properly. So to fix the issue, you need to delete that new class definition or remove the document containing that definition. In the next release, the copyDocument operation will also not copy the custom mapping, so that any copied class will not be custom mapped anymore. Thanks Jeremie for your help.

Hi all, Some news: I eventually could migrate successfully to XWiki 4.1.3 after db cleanups (thanks again Denis). I could start and browse my wiki as expected. Before re-importing the default xar pages, I decided to directly move to 4.1.4 to target very last version. I basically shutdown tomcat, backup conf (xwiki.cfg, xwiki.properties, hibernate), installed new 4.1.4 war and exploded it, merged my previous configuration files with new ones, and also put back needed libraries (some custom libs + the needed for workspaces application). At startup the context xwikitest fails to deploy, and there's not much in the logs to understand: Oct 15, 2012 12:10:59 PM org.apache.catalina.session.StandardManager doLoad FINE: Loading 0 persisted sessions Oct 15, 2012 12:10:59 PM org.apache.catalina.session.StandardManager doLoad FINE: Finish: Loading persisted sessions 2012-10-15 12:11:00,381 [main] DEBUG .c.a.ComponentAnnotationLoader - Ignored component [org.xwiki.observation.remote.internal.converter.SerializableEventConverter] since its priority level of [1000] is lower than the currently registered component [500] which has a priority of [{}] 2012-10-15 12:11:00,384 [main] DEBUG .c.a.ComponentAnnotationLoader - Ignored component [org.xwiki.observation.remote.internal.converter.SerializableEventConverter] since its priority level of [1000] is lower than the currently registered component [500] which has a priority of [{}] Oct 15, 2012 12:11:00 PM org.apache.catalina.core.StandardContext start SEVERE: Error listenerStart Oct 15, 2012 12:11:00 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/xwikitest] startup failed due to previous errors Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager stop FINE: Stopping Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager doUnload FINE: Unloading persisted sessions Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager doUnload FINE: Saving persisted sessions to SESSIONS.ser Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager doUnload FINE: Unloading 0 sessions Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager doUnload FINE: Expiring 0 persisted sessions Oct 15, 2012 12:11:00 PM org.apache.catalina.session.StandardManager doUnload FINE: Unloading complete Oct 15, 2012 12:11:00 PM org.apache.catalina.startup.ContextConfig stop FINE: ContextConfig: Processing STOP I tried to remove "logback.xml", or to set root logger as debug, but there's nothing more in the logs.
