Affects Version/s: 11.6, 11.6.1
Fix Version/s: None
Environment:Windows 10 Pro 64 bit, Chrome 76, Edge 18, Firefox 68, using a local instance XWiki 11.6.1 and 11.6 on HSQL 2.5.0, MySQL 5.7, Oracle 12c and PostgreSQL 11
STEPS TO REPRODUCE
- Create an older instance of XWiki (e.g. 8.4.6 and/or 10.11.9)
- Close the instance
- Go to the newer instance (11.6 or 11.6.1) and copy/cut the
folder and replace it (first delete the old one) in the same location on the older version
- Start XWiki and follow the Distribution Wizard through the upgrade process
The upgrade process is completed successfully without errors.
As the instance is initializing, there are encountered some consistent warnings/errors in console.
The database fails to be migrated and the browser gets 'HTTP ERROR 500'.
However, when upgrading from XWiki 10.11.9 to 11.6.1, there are encountered almost the same errors, the instance is initialized, but it's still not being properly migrated (screenshots attached).
Please also find attached the full logs from upgrading XWiki 8.4.6 to 11.6.1 on MySQL 5.7 and from XWiki 10.11.9 to 11.6.1 on HSQL.
The issue does not reproduce when upgrading to XWiki 11.5 or 11.3.2.
