Hi Federico, Release 4.1.1 is not a really good choice for migrating. There are still a couple of migration issues in that release. I advise you to migrate to 4.5.4 to be really safe with migration. If you continue to have migration issue with that version, please provide the container logs to diagnose the issue. Be careful to properly merge your xwiki.cfg file with the distributed one, and to let migrations run on all databases.

Hi! I'm Federico and I'm working with XWiki Enterprise 3.1. I have some problems in the app, for example, when I tried to assign rights to any user. Attach screen of error and a txt file with the stack trace of exception.

For try to solve this, I've imported the xwiki database to the version 4.1.1. The restore in PostgreSQL didn't give any errors. But when I tried to access, the application shows me this exception in the browser: Exception while switching to database xwiki Wrapped Exception: Database xwiki needs migration(s), it could not be safely used! (Attach file with the full stack trace) I am using PostgreSQL 9.1. In the file xwiki.cfg, I have configured the migration with the next line: xwiki.store.migration=1. So, I don't understand why fails. Maybe my database is corrupted and this is the cause of the problem. But I don't know how I solve this.

When I tried to import the xwiki in .xar format, the log in catalina.out shows this: 2013-07-26 16:17:43,752 http://localhost:9001/xwiki/bin/get/XWiki/XWikiPreferences?xpage=packageinfo... WARN c.x.x.p.p.Package - Failed to parse document [Disney/GlosarioTecnico.xml] from XML during import, thus it will not be installed. The error was: Error number 2002 in 2: Error parsing xml Wrapped Exception: Truncated ZIP file Nested exception: Truncated ZIP file

The information that I've found in Internet was not very useful to resolve the problem, for this reason, I decided to write you. I hope that you can help me with this.

Thanks!
