Backward Compatibility and Migration Notes

General Notes

• When upgrading make sure you compare and merge the following XWiki configuration files since some parameters may have been modified, removed or added:
  • xwiki.cfg
  • xwiki.properties
  • web.xml
  • hibernate.cfg.xml
• Add xwiki.store.migration=1 in xwiki.cfg so that XWiki will attempt to automatically migrate your current database to any new schema. Make sure you backup your Database before doing anything.

Issues specific to XWiki 12.6.1

In XWiki 12.6 we introduced a new store for storing notification events. We strongly recommend to use the Events migrator introduced in 12.6.1, to copy the notification events from the old store to the new one, as otherwise you won't see the old events anymore in your wiki. There are 2 ways to run it:

• From the Distribution Wizard:

  
  

• In the Wiki Administration:

  

Note that this migration can take a long time, depending on how many events you had in your wiki.
