New migration R40000XWIKI6990
A new id migration procedure is now used per default. It provide a 200x speed improvement compare to the original one, but in some rare cases, it could failed to migrate your database properly. It is really important that you keep a backup of your database ready in case of failure. If you encounter an issue with this new faster procedure, you may want to try the older procedure by first restoring your original database, and by adding the following line in your xwiki.cfg before restarting xwiki.
This will trigger the old, slower, but potentially safer mode for migrating your data.
If you still encounter issues while migrating your data, please ask us on our user mailing list and do not forget to provide a link to your failing logs so we may provide helpful hints.
