  We are not upgrading XWiki at all, we created a new

 In short:
 Our ICT created a new ubuntu server with TomCat7, Java7 and localhost MySQL
 server.
 They then put xwiki.war in the TomCat7 folder.
 They made an SQL dump of the "old" XWiki and restored that on the new MySQL
 server (and created an xwiki user with all priveleges to the xwiki
 database).
 They edited the Hibernate file so it refers to the new xwiki database.
 They edited setenv.sh with the settings for the Java Heap Space.
 
  They then opened/started XWiki and SKIPPED the upgrade
(it's not an upgrade
 but a new server).
 
Using a new XWiki war (with a different version) with an old (existing)
database (=wiki pages) is an upgrade. The wiki pages are using APIs
provided by the war. If you change the war version you need to update the
wiki pages. The job of the Distribution Wizard you skipped is to ensure the
wiki pages are in sync with the war version.
