Atlassian Data Center EOL: testing an open-source migration path

I work at XWiki, and we’ve been getting a lot of questions from teams that need to stay on-prem after Atlassian Data Center’s end of life. Together with OpenProject, we’ve built a setup that covers most Confluence + Jira use cases, fully open-source and self-hostable.

Next week, we’re doing a live session to show how migrations work, what tools we use for importing spaces, issues, and attachments, and what still needs improvement.

If you’re running on-prem or testing other open stacks after Atlassian, I’d be interested to hear what approaches you’ve tried.
