Hi Àlex, Sorry for this late reply. I need a larger extract of your logs to be able to help and probably more later. You may send it to me privately if you prefer.

Àlex, This is definitely an unexpected issue, but not an issue from the migration. It is however difficult to know which version has introduce it, and if the issue is still in the latest one. I would bet it isn't. Maybe, the best way to get around that issue, would be to rename the first document, so you will get access to the second one, and be able to rename it as well. Later you may rename the first one back. If you start hacking the database, you risk to introduce some inconsistencies, so I do not recommend that. For example, your proposed delete statements does not take care of objects, if any are attached with the document.

I was able to find the database record that made the migration process fail by rising the log level to debug. I'll explain in case someone else finds a similar problem. The problem was a wiki page that somehow got duplicated or created twice, but with a slightly different name. Moreover, although the two database records had different document ids, the id migration process assigned the same final id for both of them. The records look like this in the database: xwd_id | xwd_fullname | xwd_name | xwd_title | ----------+-------------------__-----------------------+------__----+-------------------------__-----------+ 292584123 <tel:292584123> | Main.Cursos per a professorat 2011.2012 <tel:2011.2012> | 2012 <tel:2012> | Cursos per a professorat 2011/2012 <tel:2011%2F2012> | 971984561 | Main\.Cursos per a professorat 2011.2012 <tel:2011.2012> | 2012 <tel:2012> | Cursos per a professorat 2011/2012 <tel:2011%2F2012> | xwd_date | xwd_content_update_date | xwd_creation_date | xwd_author | xwd_content_author ---------------------+--------__-----------------+------------__---------+---------------+----__----------------+ 2011-10-25 20:30:10 | 2011-10-25 20:30:10 | 2011-08-26 13:30:42 | XWiki.user1 | XWiki.user1 2012-11-12 11:25:30 | 2012-11-12 11:25:30 | 2011-12-13 15:41:49 | XWiki.user2 | XWiki.user2 xwd_creator | xwd_web | xwd_version | xwd_parent ----------------+-------------__-----------------------+------__-------+------------- XWiki.user2 | Main.Cursos per a professorat 2011 <tel:2011> | 146.1 | Main.BETSEA XWiki.user1 | Main.Cursos per a professorat 2011 <tel:2011> | 22.1 | Main.BETSEA The rest of the fields either have the same values or are empty. As can be seen in xwd_fullname, it looks like the dot on the page name might have confused XWiki. In fact, if get to the page from the web interface, the name of the page is "2012 <tel:2012>". It is as if XWiki had split the name at the "." and had taken the previous string as the space name. The URL looks like this: http://intranet-sbd.udl.cat/__xwiki/bin/view/Main.Cursos+__per+a+professora… <http://intranet-sbd.udl.cat/xwiki/bin/view/Main.Cursos+per+a+professorat+2011/2012> and in the toolbar the following appears: SPACE: Main.Cursos per a professorat 2011 <tel:2011> PAGE: 2012 <tel:2012> This is for the first record in the database. I couldn't access the second one from the web interface. By deleting the page corresponding to the first record, the migration process finishes without problems. Now I'd like to instead remove the references to the second page from the database. Would it be enough to remove the entries with the following commands? delete FROM xwikidoc where xwd_id=292584123 <tel:292584123>; delete FROM xwikiattachment where xwa_doc_id=292584123 <tel:292584123>; delete FROM xwikilinks where xwl_doc_id=292584123 <tel:292584123>; delete FROM xwikircs where xwr_docid=292584123 <tel:292584123>; If you think this might be a bug that should be solved, I still can send the logs or provide any information needed.
