Vikunja is worth evaluating with a real project containing subtasks, due dates, labels, reminders, attachments, and shared access. A simple imported task list cannot tell you whether the working system moved successfully.
Export a small, non-sensitive project from your current tool and import it into Vikunja. Count tasks and completed items, inspect dates and time zones, then verify assignees, labels, and task descriptions. Create a recurring task and see what your connected calendar or task client actually receives. Finally, export Vikunja's data and rehearse a restore on a separate instance.
Vikunja documents import and export options and CalDAV support with specific field limitations. Check your installed version and integration before promising a seamless migration. The trial passes only when a teammate can continue a live project without rebuilding its context.
