XWiki
From 15.02.2024 the manufacturer support for the Atlassian services ends. This affects the Confluence wiki service (https://confluence.desy.de), among others.
In order to continue to offer a central wiki service, IT will provide the product XWiki from the beginning of 2024. You may reach the service via https://xwiki.desy.de.
End of July 2024 - Begin of the automated Migration
|
From the end of July, the automated migration of Confluence Spaces to XWiki (https://xwiki.desy.de) will begin as follows:
Automated migration into the Test-System (https://it-xwiki-tst.desy.de) with agreed procedure:
Overall: All other spaces to be discussed manually For further details please see further down on this page |
30.01.2024 - Begin of the first Migrations to the Test Server

Migration from Confluence to XWiki
The migration of data from Confluence to XWiki is performed centrally by DESY-IT. No special preparations or precautions are required on the part of the users. However, it may be helpful for the migration to note the following points and apply them where possible:
- Remove macros that reference content from Bitbucket, Bamboo or Jira
- Remove macros that already do not work in Confluence
- Remove content that is no longer needed
- Update space permissions if required, especially Administrator-rights, as these are used for contacting the correct users during the migration process.
When and how to migrate?
Standard procedure
For standard cases, spaces are migrated into the preview system first, to review all space contents. After that, spaces are migrated into the production ("normal") XWiki-instance.
The standard procedure of data migration is planned as follows described below. For the migration, several Spaces are bundled and migrated collectively.
|
Very small and old spaces
Following spaces will be migrated directly into the production-instance (https://xwiki.desy.de):
- Spaces with only one page
- Spaces which haven't been edited in the last year, starting with the oldest
The Process is as follows:
- Migration of the space into the production-instance (https://xwiki.desy.de)
- Space-admins are notified
How will be communicated?
Space-admins serve as the primary contacts during the migration process. After every migration the admins will be notified about the completed process. If a space has more then 5 or no admins, the creator of the space will be contacted instead, if possible. As a consequence, a maximum of 5 users will be contacted per space.
Are major reworks required?
As we have experienced so far, no major reworking is required for simple text content. Only the page layout may look slightly different after the migration than before, which may result in smaller line spacing or similar at one point or another. If desired, appropriate reworking may be useful here to improve the readability of the content.
Macros
If macros are used on your Confluence pages, you may encounter error messages after the migration (indicated by a clearly visible pink box) because the macro no longer works. For most Confluence macros, there is a corresponding replacement in XWiki that can be used instead of the previous macro. Further information will be available shortly in the FAQ of the DESY XWiki service.
Diagrams
The standard diagram-tool for XWiki is DrawIO. During the transitional phase, Gliffy has been installed, which was used in confluence to create diagrams. All diagrams are therefore migrated and displayed, but can only be edited after manually converting them to a DrawIO-Diagram using the button "Convert". This action is usually required before a diagram can be edited.
Access to Confluence after the migration
Your Confluence space will be switched to read-only mode after the migration of its content to the XWiki production system (https://xwiki.desy.de). This means that on your XWiki space no more changes can be made to in Confluence after the migration to the procution system.
When is the migration phase completed?
In total, there are ~3000 confluence spaces which have to be migrated into XWiki. Around half of these a fullfilling the conditions mentioned above (only one page or last edit was more then one year ago.) Therefore, around 1500 spaces can be migrated directly into production, without the need to migrate into the preview-system first. For all other spaces, two migrations (preview-system and production) are necessary.
Overall, there are severel thousand migrations to be performed. Depending on the size of the space, the migration can take up to one hour or longer. It is currently planned to complete all essential migration tasks until the end of 2024.
Documentation
If anything is unclear about the use of XWiki, please first consult the official XWiki documentation and the DESY XWiki FAQ. The DESY XWiki FAQ contains the most frequently asked questions and answers. These will be continuously expanded, especially during the introductory phase of XWiki at DESY.
