XWiki is a FOSS knowledge management solution, and a direct alternative to the Confluence, the wiki part of the Atlassian software suite, along with Jira or Bitbucket. XWiki and Confluence share similarities in their approach, including an extension mechanism and the possibility to write macros in wiki pages, which enables users to create dynamic contents.

Today, following changes in Atlassian's policy when it comes to handling on-premise licenses [1], companies are looking to migrate away from Confluence to limit lock-in and to take back ownership on their data. However, migrating from such complex systems comes with its own set of challenges, both when it comes to the financing of migration tools and the implementation of technical alternatives to functionalities in proprietary software.

In this talk, we will dive into some of the technical aspects that make a migration from complex proprietary tools difficult. We will also look into how we chose to build and finance the development of Open Source migration solutions to make the switch from Confluence to XWiki.
